Classification of transducer
1) Transducer and inverse transducer
2) active and passive transducer
3) primary and secondary transducer
4) analog and digital transducer
First we are discussing
1. Transducer and inverse transducer
Transducer is a device which physical signal concerted to Electrical signal
Inverse transducer is a any Electrical signal concerted to a physical quantity
Examples- speaker
2. Active Transducer
It is a transducer which converts one from of energy in to other from of with out use of any axulary power source
EX- solar cell, photovoltaic cells
3. Passive transducer
It is a device which converts one from of energy into other from with the use of any axulary power source
EX- photovoltaic cells, bridge.
3. Analog transducer
It converts the input quantity into an analog output which is the continuous function of time
EX- strain gauge
4 digital transducer
It converts input quantity into an electrical quantity which is in the form of pulse
Ex- rectifier,full wave rectifier
