Electrical Engineering ⇒ Topic : Classification of transducer
Classification of transducer
(A) Transducers are broadly classified into two groups as
Active transducers Examples Thermocouple and thermopiles, piezoelectric pickup, photo voltanic cell.
Passive transducers Examples Resistance thermometers and thermistors,potentiometric devices, differential transformer, photoemissive cell
(B) Classification based on the type of output.
I. Analogue transducers Examples Strain gauge, a thermocouple, a thermistor or an LVPT.
2. Digital transducers Examples Pulses
(C) Classification based on electrical principie involved.
1. Variable resistance type
2. Variable-inductance type
3. VariableCapacitance type
4. Voltagegenerating type
5. Voltage-divider type
