Sensors Used in Instrumentation and Control

Ammeter - A meter to indicate electrical current. It is normally part of a DMM.

Bellows - This is a flexible volume that will expand or contract with a pressure change. This often looks like a cylinder with a large radius (typ. 2") but it is very thin (type 1/4"). It can be set up so that when pressure changes, the dis-placement of one side can be measured to determine pressure.

Bourdon tube - Widely used industrial gage to measure pressure and vacuum. It resembles a crescent moon. When the pressure inside changes the moon shape will tend to straighten out. By measuring the displacement of the tip the pressure can be measured.

Chromatographic instruments - laboratory-type instruments used to analyze chemical compounds and gases.

Inductance-coil pulse generator - transducer used to measure rotational speed. Output is pulse train.

Interferometers - These use the interference of light waves 180 degrees out of phase to determine distances.
Typical sources of the monochromatic light required are lasers.

Linear-Variable-Differential transformer (LVDT) electromechanical transducer used to measure angular or linear displacement. Output is Voltage

Manometer - liquid column gage used widely in industry to measure pressure.

Ohmmeter - meter to indicate electrical resistance.

Optical Pyrometer - device to measure temperature of an object at high temperatures by sensing the brightness of an objects surface.

Orifice Plate - widely used flowmeter to indicate fluid flow rates

Photometric Transducers - a class of transducers used to sense light, including phototubes, photodiodes, phototransistors, and photoconductors.

Piezoelectric Accelerometer - Transducer used to measure vibration. Output is emf.

Pitot Tube - Laboratory device used to measure flow.

Positive displacement Flowmeter - Variety of transducers used to measure flow. Typical output is pulse train.
Potentiometer - instrument used to measure voltage.

Pressure Transducers - A class of transducers used to measure pressure. Typical output is voltage. Operation of the transducer can be based on strain gages or other devices.

Radiation pyrometer - device to measure temperature by sensing the thermal radiation emitted from the object.

Resolver - this device is similar to an incremental encoder, except that it uses coils to generate magnetic fields. This is like a rotary transformer.

Strain Gage - Widely used to indicate torque, force, pressure, and other variables. Output is change in resistance due to strain, which can be converted into voltage.

Thermistor - Also called a resistance thermometer; an instrument used to measure temperature. Operation is based on change in resistance as a function of temperature.

Thermocouple - widely used temperature transducer based on the Seebeck effect, in which a junction of two dissimilar metals emits emf related to temperature.

Turbine Flowmeter - transducer to measure flow rate. Output is pulse train.

Venturi Tube - device used to measure flow rates.

i hope you enjoyed this post, comment me for any clarification.

Spiral bimetallic thermometer

Basic principle of Spiral bimetallic thermometer

When a bimetallic spiral fixed at one end and free at the other end is subjected to a temperature change, the free end of the bimetallic spiral deflects proportional to the change in temperature. This deflection becomes a measure of the change in temperature.

Description of Spiral bimetallic thermometer

construction of Spiral bimetallic thermometerThe main parts of a spiral bimetallic thermometer are as follows:
A bimetallic spiral which is fixed at one end to the body of the instrument and free at its other end.
To the free end of the bimetallic spiral is attached to a free floating shaft.
One end of the shaft is mounted in a fraction less arrangement and its other end is connected to a pointer which sweeps over a temperature calibrated circular dial graduated in degrees of temperature.

Operation of Spiral bimetallic thermometer


image of Spiral bimetallic thermometerWhen a temperature of a medium is to be measured, the bimetallic thermometer is introduced into the medium for a length ‘L’

The bimetallic spiral senses the temperature and expands resulting in a deflection at its free end.

This deflection at the free end of the bimetallic spiral rotates the free floating shaft connected to it. When the free floating shaft rotates, the pointer attached to the shaft moves to a new position on the temperature calibrated dial including the measured temperature.

Ultrasonics – Introduction.

Vibrations upto 20,000 cycles can be heard by human beings and so, the frequency range upto 20KHz is called sonic frequency. Sound waves do not belong to the electromagnetic wave family like heat and light. As such, study of sound waves is not exactly an electronic branch. However most of the ultrasonic sound waves find very valuable industrial applications as flaw direction, submarine communication, electronic soldering and welding.

Ultrasonics is today applied in medical diagnosis (echo-scanning) as an alternative to X-ray scanning. Production of ultrasonic sound waves involves use of electronic oscillators called transducers. Use of ultrasonic waves does not involve harmful wave radiation. Radiation is present in other methods for the applications mentioned above. Hence ultrasonics is a welcome substitute for electromagnetic waves in many industrial applications.

Properties of ultrasound.


The ultrasonic waves travel in different media with different velocities. In air it travels at 330m/sec. The velocities in liquids and solids range from 1200m/s to 4000m/s respectively. The property of a medium to conduct ultrasonic waves is represented in its acoustic impedance. When ultrasound travels through a homogeneous medium there is not change of velocity or wavelength and hence it essentially continues in a straight line. When the ultrasound beam reaches an interface between two different media, it undergoes reflection and refraction.



The reflected wave may be termed as the ultrasonic echo. The echoes produced by large objects with smooth surface are specular echoes. Much energy is returned by these specular echoes. Echoes from small objects with irregular shapes are called scattered echoes. When ultrasound gets reflected irregularly in multiple directions, only a small part of ultrasonic energy returns to the source. Through analysis of reflected waves leads to several useful applications in industry and medicine. The properties of ultrasound are summed up as follows:

Ultrasound
  1. Can be directed into a beam.
  2. Obeys laws of reflection and refraction.
  3. Is reflected by small objects.
  4. Permits recording of clear echoes from interface that are approximately 1 mm part.

A Complete Note on Difference between Lab View, PLC and DCS

Yesterday, i receive a question from one of my facebook fan asking " sir could u please say the difference between labview and plc and dcs "

As far as i know Lab View is completely different from DCS and PLC, Labview is a software.

LabVIEW is a graphical programming environment used by millions of engineers and scientists to develop sophisticated measurement, test, and control systems using intuitive graphical icons and wires that resemble a flowchart. It offers unrivaled integration with thousands of hardware devices and provides hundreds of built-in libraries for advanced analysis and data visualization – all for creating virtual instrumentation. The LabVIEW platform is scalable across multiple targets and OSs, and, since its introduction in 1986, it has become an industry leader.

A distributed control system (DCS) refers to a control system usually of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system with each component sub-system controlled by one or more controllers. The entire system of controllers is connected by networks for communication and monitoring.

A programmable logic controller (PLC) or Programmable controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures. PLCs are used in many industries and machines. Unlike general-purpose computers, the PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact. Programs to control machine operation are typically stored in battery-backed-up or non-volatile memory. A PLC is an example of a hard real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.

The differences between DCS and PLC are: DCS (Distributed Control System) is a CONTROL SYSTEM that works using several controllers and coordinates the work of all these controllers. Each controller is handling a separate plant. This controller is referred to the PLC.

The PLC (Programmable Logic Controller) is a CONTROLLER which can be re-program back. If the PLC is only a stand-alone and not combined with other PLCs, it is called as DDC. It means PLC is a sub system of a large system called DCS.

What’s difference between PLC and DCS by its definition:
PLC is a controller or processor that can be programmed (programmable) whose function is to run (execute) logic functions. Logic means the discrete / sequence function is usually handled by the relay. From the beginning of the vendors who carry the name of the PLC is engaged in the business discrete / sequence control.

Regardless of the distributed control system (as opposed to the DDC = Direct Digital Control) is categorized as a DCS. In DDC all system controls are done in the central processor so that if it failed, the entire control plant will also failed. DDC is mostly used as a Regulatory Control. And from the beginning vendors that carry the name of DCS is to use the product as a regulatory control.

Different in functionality means that the DCS and PLC can not be implemented on the same application.
1. DCS is not a large PLC. Because system architecture of DCS and PLC are different.
2. DCS is not PLCs that integrated into one large system. "Controller" in the PLC is more intended as a "Logic Controller", while “Controller” in the DCS is more intended as a "Process Controller".
3. Both DCS and PLC is a configurable and reconfigurable.

Distributed Control System - Architecture Part 2

This part is the continuation of my previous post on Distributed Control System - Architecture. The figure below shows a generalized architecture of disturbed control system.

The explanation of each block is given below:

Local control unit (LCU)

The smallest collection of hardware in the system that can do closed – loop control. The LCU interfaces directly to the process.

Low level human interface (LLHI)

A device that allows the operator or instrument engineer to interact with the local control unit (e.g to change set points, control nodes, control configuration or tunning parameters) using a direct connection. LLHI’s can also interface directly to the process. Operator oriented hardware at this level is called low level operator interface, instrument engineer – orientated hardware is called a low level operator interface, instrument engineering interface.

Data Input / output unit (DI/OU)

A device that interfaces to the process solely for the purpose of acquiring or outputting data. It performs no control function.


High level human interface (HLHI)

A collection of hardware that perform functions similar to the LLHI but with increased capability and user friendliness. It interfaces to other devices only over the shared communication fatuities. Operator – oriented hardware at this level is called high level operator interface, instrument engineer oriented hardware is called high level engineering interface.

High level computing device (HLCD)

A collection of micro processor based hardware that performs plant management functions traditionally performed by a plant computer. It interfaces to other devices only other the shared communication facilities.

Computer interface devices (CID)

A collection of hardware that allows an external generate purpose computer to interact with other devices in the distributed control system using the shared communication facilities.

Shared communication facilities

One or more levels of communication hardware and association software that allows the sharing of data among all devices in the distributed system should communicate channels between specific devices as between hardware elements within a device.

It is the most important round of the selection process. The first three sections are easy & if you prepare well for aptitude from R S Agrwal. Then it won’t be a problem. But the time is very less so u must be fast.

For the technical section, they asked basic question from the whole instrumentation. for this Section u must prepare well. They asked from all the subject of previous semester. So the basic fundamental must be clear.

Some of questions like....
  1. Range of any specific type thermocouple.
  2. About plc & dcs.
  3. Digital technology.(flip-flop etc...)
  4. Transducers & their principles.
  5. op-amp based question.
  6. 4-20ma related questions.
After this written section the result was declared & fortunately i was selected for group discussion.

Group discussion:
This part is put just for formality. No one was eliminated from this round.

Personal interview:-
There were two sections in personal interview.
  1. Technical.
  2. HR.

In technical, they asked me about myself, and then start some technical question related to plc & dcs. Control valves, three element boiler control, and cascade, discuss my 8th semester project. The sir was very friendly & asks me about my interest & it was great experience. The main thing is your confidence & must be confident.

In HR, they asked me very simple question like why do u want to join essar? , family background, why don’t u want to study further. just answer honestly. Don’t be over smart. After 15 days they send result to out college TPO. & i was selected.

Distributed Control System - Architecture

This post is a continuation of my previous post on Distributed Control System

The structure of a DCS is often referred to as its architecture. In terms of functional modules, DCS’s from various vendors have lot in same. The image below gives the architecture of generalized DCS. The following major inter connected technologies have been used for distributed control.

  1. Shared bus
  2. Ring and
  3. Hierarchical.
In shared bus systems the connected processors communicated over a common channel using time-sharing, thus allowing attached computers to transmit information in short-duration, high speed bursts.


A ring system consists of high speed, unidirectional digital communication channel (e.g. fiber optics link, twisted-wire pair, etc.) which’s arranged as a closed loop or ring microcomputers are attached to the ring by ring – interface units.

A hierarchical system consists of number of minicomputers or microcomputers inter connected in a tree structure.

The data collection and direct – control activities are handled at the lowest level, where as data processing, summary processing and co ordination are performed at higher levels.

The proper selection of architecture including software and type of processors greatly influences the performance of the distributed control system. Variations in the architecture are determined by several factors, such as memory size and rate, data paths between computers, usage flow control and error checking and recovery.

In the next post, I will discuss about the distributed control system architecture in depth.

The Zener Diode

Electronic Devices plays an important role in sensors and controllers which are the two eyes of instrumentation and control engineering. So i am slowly going to discuss about the important electronic devices in our blog.

Zener diode is a specially designed PN junction diode. a reverse biased, heavily doped PN junction diode which is operated in the breakdown region is known as zener diode. It is also called a voltage regulator diode or breakdown diode.

Construction of Zener Diode:

zener-diode-symbol

zener-diode-constrctionFigure 1 shows the symbol of a zener diode. it is similar to the symbol of an ordinary PN junction diode except that its bar is just turned into Z shape. Figure 2 shows a practical equivalent circuit of a zener diode. this circuit shows that a zener diode is equivalent to a battery with voltage (Vz) called zener voltage in series with a resistance (rz) called zener resistance.

Working Principle of Zener Diode:


We will see the working of zener diode as two sections like forward bias and reverse bias.

Forward bias:

zener diode forward bias

Figure 3 shows the arrangement for forward bias. The positive terminal of the battery is connected to the anode (A) and the negative terminal of the battery is connected to the cathode (K). When applied voltage is zero no current flows through the zener diode. when the forward biasing voltage is increased the potential barrier is reduced and the current starts flowing in the circuit.

Reverse Bias:

zener diode reverse bias

Figure 4 shows the arrangement for reverse bias. The negative terminal of a battery is connected to the anode (A) and positive terminal of the battery is connected to cathode (K). the reverse bias operation is explained in VI characteristic.

V-I characteristic of zener diode.

v-i-characteristics-of-zener-diode

The forward and reverse V-I characteristic shown in the figure 5. The forward current increases slowly upto the knee voltage. Beyond this voltage the current increases sharply with increase in applied voltage. Thus under forward bias condition zener diode acts like an ordinary PN junction diode.

Under reverse bias condition a small reverse current flows through the zener diode. When a reverse voltage across a zener diode is increased, a critical voltage called breakdown voltage is reached at which the reverse current increases sharply as shown by the curve PQ in the figure 5. This breakdown voltage is called zener breakdown voltage or simply zener voltage. This voltage is almost constant over the operating region. This ability of a diode is called regulating ability and is an important feature of a zener diode. It maintains an essentially a constant voltage across its terminal over a specified range of zener current values.

Vz – Zener breakdown voltage.
Iz (min) – A minimum value of zener current called break over current.
Iz (max) – A maximum value of zener current above which the zener diode may be damaged.

Zener break-down


Zener breakdown takes when both sides of the junction are very heavily doped and the depletion layer is thin. When a small reverse voltage is applied a very strong electric field is set up across the thin depletion layer. This electric field is enough to break the covalent bonds. Now extremely large number of free charge carriers are produced which constitute the zener current. This process is known as zener breakdown. In this process the junction is not damaged. The junction regains its original position when the reverse voltage is removed.
Zener+break-down+%2526+Avalanche+Break-down

Avalanche breakdown


The avalanche breakdown takes place when both sides of the junction are lightly doped and the depletion layer is large. When the reverse bias voltage is increased, the accelerated free electron collides with the semiconductor atoms in the depletion region. Due to the collision with valence electrons, covalent bonds are broken and electron-hole pairs are generated. These new charge carriers so produced acquire energy from applied potential and in turn produced additional carriers. This forms avalanche multiplication. This avalanche multiplication causes the reverse current to increase rapidly. This leads to avalanche breakdown. Once this breakdown occurs the junction cannot regain its original position. This breakdown occurs at higher reverse voltage as shown in the figure 6.

Applications of zener diode.


  • It can be used as a voltage regulator.
  • It can be used as a limiter in wave shaping circuits.
  • It can be used as a fixed reference voltage in transistor biasing circuits.
  • It is used for meter protection against damage from accidental over voltage.
  • It can be used as a fixed reference voltage in a network for calibrating voltmeters.

Torque Equation for PMMC

This post is a continuation of my previous post on Permanent magnet moving coil instruments . This post is written since a is request made by the face book user Shivany Sweet


Torque Equation for PMMC

The equation for the delevoped torque of the PMMC can be obtained from the basic law of electromagnetic torque. The deflecting torque is given by,

                                                   Td = NBAI

Where,
Td = deflecting torque in N-m
B = flux density in air gap, Wb/m2
N = Number of turns of the coils
A = effective area of coil m2
I = current in the moving coil, amperes

Therefore, Td = GI
Where, G = NBA = constant

The controlling torque is provided by the springs and is proportional to the angular deflection of the pointer.
                                               Tc = KØ

Where,
Tc = Controlling Torque
K = Spring Constant Nm/rad or Nm/deg
Ø = angular deflection
For the final steady state position,
                        Td = Tc
Therefore GI = KØ
So,                      Ø = (G/K)I          or            I = (K/G) Ø

Thus the deflection is directly proportional to the current passing through the coil. The pointer deflection can therefore be used to measure current.

Distributed control system:

Definition:

A collection of processing elements, which are inter connected both logically and physically with decentralized system, wide control of resources for co-operative execution of application programs.

A DCS consists of a number of microprocessor – based modules that work together to control and monitor a plant’s operations. The modules are distributed graphically.

Distributed processing is useful in process control for the following reasons:

  1. DCS gives increased performance through resource sharing.
  2. Increased reliability.
  3. Modularity and expandability.
  4. Reduced cabling cost (i.e., field wiring and installation)
  5. It also reduces risk by distributing the control function throughout a number of small modules rather than concentrating it in one large module.

Disadvantages of Distributed control system:

Increased software development cost, more complex failure diagnosis and dependence on communication technology. These have been over come to a great extent by the development of high – level languages and structured – programming concept, communication technology (e.g. fiber optics) and fault – diagnosis methods.

In my next post, I will explain about DCS Architecture.

ABB wins Eskom upgrade contract - Instrumentation News

POWER and automation technology group ABB has won an order from Eskom for the provision of new equipment for the utility’s Arnot power station in Mpumalanga.

ABB yesterday said its control and instrumentation system would integrate Arnot’s water treatment plant, condensate plant regeneration, condensate polishing plant, and ammonia and sedimentation plant into one common plant network.

The scope of the project, which started this month, includes design, production engineering, factory testing, delivery, installation, commissioning, operational acceptance testing, plant documentation and training, ABB said.

The project would be implemented over 20 months, ABB said.

"ABB experts have engaged with the customer to develop operation and control philosophies for implementing on our control system. This will fully automate and allow remote central operation of the plant and provide a safer working environment for plant workers," Carlos Pone, country manager of ABB SA, said yesterday.

The need to upgrade Arnot arose because of the current manual operation with dangerous chemicals and the labour-intensive working environment where operators might be prone to errors, ABB said.

Eskom is investigating the circumstances that led to a blast in its Duvha power station earlier this year. The reasons for the accident, which has taken out 600MW from the national electricity system, are still unknown.

Eskom CE Brian Dames last month said that the unit, which was damaged in the accident, could be returned to service by next June.

ABB said it had recently completed the Kendal power station water treatment plant, which uses the same technology platform as offered for Arnot.

"ABB has an experienced engineering team with water treatment plant process knowledge and because safety is important not just for us at ABB but for our customers , we are pleased to provide automation solutions that address the plant safety issues," Mr Pone said.

This is the latest of several contracts that ABB has won from Eskom. These include a two-year contract for the expansion and replacement of high-voltage products for the transmission network in the country.

ABB said that power utilities and municipalities in Southern Africa and sub-Saharan Africa are investing in improving infrastructure to ensure reliable power supply.

Automatic Mains Failure Solution - Instrrumentation Project

Now a days we often see power cut every now and then, mains supply fails at any time of the day without prior information, this causes lot of trouble specially during summer. Life gets almost paralized without an electric power.Power inverters and ups solves this problem up to certain extend for low power consumers, specially household domestic loads and small shops can make use of this type of solution.


instrumentation projectsBut industrial sector gets effected more with power cut. Industries have now started installing diesel generator sets in their units. Even larger societies in the Metro cities have started installing diesel generator sets. Manual starting of the generator takes some time and causes panic to the people struck inside the lift compartment when the supply fails suddenly. Other people equally get effected other places.

It provides reliable and accurate start/stop operation of the D.G.SET with AUTO LOAD CHANGE OVER FROM D.G.AND MAINS and FAULT ANNUNCIATION for the safety of the D.G. SET

This project is a proper solution to the above problem as name stands AUTO MAIN FAILURE SOLUTION (AMFS). What it dose ?

It senses the main supply failure and give starting pulse to diesel generator through start solenoid.

If the generator dose not get started with the first attempt ,it will make two more attempts to start the D.G.set. When it fails to start with three attempts, it will sound an alarm with indication “ STRAT FAIL”.

Even if the engine starts normally but alternator dose not produce the required voltage, in that case “ALTERNATOR FAIL” signal will come.

After the gen set has started normally and it has come to normal voltage ,it will switch on its breaker automatically (auto-on-load).

During normally running condition, if any fault occurs on the engine side, it will stop automatically with the respective fault and buzzer indication.

when the main supply get re-stored, it will change over to mains and switch off the D.G. set automatically.

It can be operated on both auto or manual mode.

Comment me if interested..

Programmable Logic Controller - PLC


Hello friends, in this post I am going to start sharing a information related to a new topic Programmable Logic Controller which plays a very important role in automation of every industry.

Evolution of PLC ?


Manufacturing process require a sequence of operations in order to make a product.
And in this case sequencing can be done by manually or some type of controller.
In late 1960’s sequencing operations are performed by using a bank of relays wired to perform a particular job.
But there were drawbacks, logic systems where difficult to reprogram for production changes and also troubleshooting is very difficult.

To avoid the above drawbacks PLC’s are used.

PLC’s use the sum relay logic function and sequence is not hard wired but can be programmed and stored in a memory.
The contents of the memory are easily changed.
PLC’s are used first by automobile industries.

How to select a Transducer ?

In a measurement system the transducer is the input element with critical function of transforming some physical quantity to a proportional electrical signal. Selection of the appropriate transducer is therefore the first and perhaps most important step in obtaining accurate results in every instrumentation and control system. A number of elementary questions should be asked before a transducer can be selected, for example,

  • What is the physical quantity to be measured?
  • Which transducer principle can be used to measure this quantity?
  • What accuracy is required for this measurement?

The first question can be answered by determining the type and range of the measurand. An appropriate answer to the second question requires that the input and output characteristics of the transducer be compatible with the recording or measurement system. In most cases, these two questions can be answered readily, implying that the proper transducer is selected simply by the addition of an accuracy tolerance. In practice, this is rarely possible due to the complexity of the various transducer parameters that affects the accuracy. The accuracy requirements of the total system determine the degree to which individual factors contributing to accuracy must be considered. Some of these factors are:

  1. Fundamental transducer parameters: type and range of measurand, sensitivity, excitation
  2. Physical conditions: mechanical and electrical connections, mounting provisions, corrosion resistance.
  3. Ambient conditions: nonlinearity effects, hysteresis effects, frequency response, resolutions
  4. Environmental conditions: temperature effects, acceleration, shock and vibration
  5. Compatibility of the associated equipment: zero balance provisions, sensitivity tolerance, impedance matching, insulation resistance.

Categories 1 and 2 are basic electrical and mechanical characteristics of the transducer. Transducer accuracy, as an independent component, is contained in categories 3 and 4. Category 5 considers the transducer’s compatibility with its associated system equipment.

The total measurement error in a transducer-activated system may be reduced to fall within the required accuracy range by the following techniques:

  1. Using in-place system calibration with corrections performed in the data reduction
  2. Simultaneously monitoring the environment and correcting the data accordingly.
  3. Artificially controlling the environment to minimize possible errors.

Some individual errors are predictable and can be calibrated out of the system. When the entire system is calibrated, these calibration date may then be used to correct the recorded data. Environmental errors can be corrected by data reduction if the environmental effects are recorded simultaneously with the actual data. Then the data are corrected by using the known environmental characteristics of the transducers. These two techniques can provide a significant increase in system accuracy.

Another method to improve overall system accuracy is to control artificially the environment of the transducer. If the environment of the transducer can be kept unchanged, these errors are reduced to zero. This type of control may require either physically moving the transducer to a more favorable position or providing the required isolation from the environment by heater enclosure, vibration isolation, or similar means.
