What Transducer Is?

A transducer is an electronic device that converts energy from one form to another. Common examples include microphones, loudspeakers, thermometers, position and pressure sensors, and antenna. Although not generally thought of as transducers, photocells, LEDs (light-emitting diodes), and even common light bulbs are transducers. A transducer plays a very important role in any instrumentation system.

Types Of Transducer:

There are many types of the transducer. Transducer can be classified into main types as below,
  • Quantity to be measured
  • Principle of Operation

Transducer as Quantity to be measured

  • Temperature transducer
  • Pressure transducer
  • Displacement transducer
  • Flow transducer

Transducer as Principle of Operations

  • Chemical transducer
  • Photovoltaic transducer
  • Photoconductor transducer
  • Half effect transducer
  • Piezoelectric transducer

Ideal Characteristics of Transducer

  • High dynamic range
  • High repeatability
  • Low Noise
  • Low hysteresis
