Advantages, disadvantages and applications of capacitive transducer

Advantages:

There are some advantages of capacitive transducer which are given below,

  • The sensitivity of capacitive transducer is high.
  • The capacitive transducer is useful for small system.
  • It has good frequency response.
  • It requires small power to operate.
  • The loading effect is less due to high input impedance.

Disadvantages:

There are some disadvantages of capacitive transducer which are given below,

  • The capacitive transducers are temperature sensitive.
  • It gives non linear behavior.
  • The output impedance depends upon the frequency used.
  • The capacitance may get changed by dust particle and moisture which produce error.

Applications:

There are some important applications of capacitive transducer which are given below,

  • The capacitive transducers are used to measure humidity in gases.
  • It is used to measure volume, liquid level, density etc.
  • It is used for measurement of linear and angular displacement.
