Moving coil Type Velocity Transducer

Basic Principle of Moving coil Type Velocity Transducer

  1. A coil moves in a magnetic field according to the velocity applied.
  2. The voltage in the coil becomes a measure of the velocity when calibrated.

Description of Moving coil Type Velocity Transducer

  1. The instrument has permanent pole pieces which generate the magnetic field.
  2. There is a pivoted arm on which a coil is mounted.
  3. There is a mass attached to the end of the coil.
  4. The whole device is contained in an antimagnetic case.

Operation of Moving coil Type Velocity Transducer

  1. The velocity to be measured is applied to the arm.
  2. Due to this coil moves in the magnetic field.
  3. A voltage is generated on account of motion of the coil in the magnetic field.
  4. The output voltage is proportional to the velocity.

Advantages of Moving coil Type Velocity Transducer

  1. The antimagnetic case reduces the effects of stray magnetic field.
  2. Damping is obtained electrically.
  3. There is high stability under varying temperature conditions.

Applications of Moving coil Type Velocity Transducer

These transducers are used for measuring velocities in linear, sinusoidal or random manner.


Moving magnet type velocity Transducer

Basic principle of Moving magnet type velocity Transducer
When a permanent magnet moves inside a coil, the change in the length of the air gap varies the reluctance. Hence the output voltage is directly proportional to the rate of change of the length of the air gap (change in length produced by velocity). Thus the output voltage becomes a measure of the velocity when calibrated.

Description of Moving magnet type velocity Transducer

    Moving magnet type velocity Transducer
  1. The sensing element which is a rod is a permanent magnet.
  2. The rod is rigidly coupled to the device whose velocity is being measured.
  3. There is a coil surrounding the permanent magnet.
  4. The permanent magnet is movable, that is, it can move in and out of the coil.

Operation of Moving magnet type velocity Transducer

  1. The instrument is fixed to the device whose velocity is to measured.
  2. Due to the application of the velocity, the permanent magnet moves in or out of the coil. Due to its motion, the length of the air gap varies.
  3. The output voltage also varies due to the motion of the magnet and the amplitude of the voltage is directly proportional to velocity.
  4. The polarity of the output voltages determines the direction of the velocity.

Advantages of Moving magnet type velocity Transducer

  1. Its maintenance is negligible.
  2. The output voltage is linearly proportional to velocity.
  3. Cost of manufacture is less.

Disadvantages of Moving magnet type velocity Transducer

  1. Performance is affected by stray magnetic fields and hence noise is caused.
  2. Frequency response is poor.
Used as a velocity transducer to convert velocity to measureable voltage.


Instruments used to measure angular velocity

Angular velocity is measured using devices called tachometers.Tachometers are instruments that measure angular speed by registering anyone of the following

Number of rotations during the contact period (or)

  • Number of rotations per minute (rpm)
  • Tachometers are classified as follows:

Mechanical Tachometers

  1. Revolution counter and timer
  2. Tachoscope
  3. Hand speed indicator
  4. Slipping clutch tachometer
  5. Centrifugal force tachometer
  6. Vibration reed tachometer

Electrical tachometers

  • Drag cup tachometer
  • Commutated capacitor tachometer
  • Tachogenerators
  • DC – Tachogeneraor
  • AC – Tachogeneraor

Contact Less Electrical Tachometers

  1. Inductive pick up tachometer
  2. Stroboscope tachometer
  3. Photoelectric tachometer
  4. Capacitor tachometer


Devices used to measure dimensions

This post contains a small list of devices used in measuring dimension. They are ,

  1. Steel rules
  2. Vernier calipers
  3. Micrometers
  4. Dial gauge indicator
  5. Gauge blocks
  6. Optical methods (Microscopes, telescopes and optical flats with a monochromatic source of light)
  7. Pneumatic comparators.
