There are two types of transducers, they are:
- Active transducers
- Passive transducers
Active transducers:
Active transducer is a device which converts the given non-electrical energy into electrical energy by itself. Thermocouple, Photovoltaic cell and more are the best examples of the transducers
Passive transducers:
Passive transducer is a device which converts the given non-electrical energy into electrical energy by external force. Resistance strain gauge, Differential Transformer are the examples for the Passive transducers.
