  1. 2. Transducers which convert light energy into electric energy for measurement purposes
  2. 6. transducer which produces their outputs in digital form or a form pulses
  3. 8. angular velocity measuring device
  4. 9. device that converts energy from one form to another
  5. 11. device which measures and converts an electrical variable into nonelectrical variable
  6. 13. Linear Variable Differential Transformer
  7. 14. sensor that measures the physical acceleration of object due to inertial forces or due to mechanical excitation
  8. 17. Photovoltaic Transducer
  9. 18. A permanent magnet is suspended between two springs and fitted with low friction bearing rings
  10. 21. operating range of the transducer should be wide, to permit its use under a wide range of measurement conditions
  11. 22. transducers need external source of power for their operation
  12. 23. motion of the magnet induces a voltage in the coil and the amplitude of the voltage is directly proportional to the velocity
  13. 24. the unit change in resistance per unit change in length

  1. 1. Primary transducer example
  2. 3. relationship between a physical parameter and the resulting electrical signal must be linear
  3. 4. transducers do not need any external source of power for their operation
  4. 5. piezoelectric material
  5. 7. Transducers based on principle that change in the magnetic characteristics of an electrical circuit in response to a physical quantity
  6. 10. movement of the coil causes a change in the flux linkages between the Magnet and the coil, and due to the electromagnetic induction voltage gets induced
  7. 12. electrical device then converts the mechanical signal into a corresponding electrical signal
  8. 14. rate of change of velocity with respect to time
  9. 15. transducers in which the resistance changes due to the change in some physical phenomenon
