Classification of transducer

Transducer:

The transducer is the electronic device which converts one form of energy into another form of energy. In electronic system the transducer converts non electrical signal (physical) into electrical signal.

Classification of transducer:

The transducer can be classified as,

  • Primary transducer

The primary transducer is also known as detector or sensor. It senses a physical parameter such as pressure, humidity, temperature etc and converts it into suitable physical parameter which is readable.

  • Secondary transducer

The secondary transducer converts the output of primary transducer into electrical signal.

  • Analog transducer

The analog transducer converts the input signal into an analog output which is continuous function of time.

  • Digital transducer

The digital transducer converts the input signal into an electrical output which is in the form of pulses.

  • Electrical transducer

The electrical transducers are that transducer which sense the physical parameter and converts it into the electrical signal.

  • Mechanical transducer

The mechanical transducers are that transducer which converts the one form of physical quantity into another form of physical quantity.

  • Active transducer

The active transducers are also called as self generating transducer. It is that type of transducer which does not require any external (auxiliary) power supply to produce output.

  • Passive transducer

The passive transducer is also known as externally powered transducer. It is that type of transducer which requires an auxiliary power supply to produce output.
