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 antennae. 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 transducers. The transducer can be classified into main types as below,
- Quantity to be measured
- Principle of Operation
