Active transducer Vs Passive transducer-Difference between Active transducer and Passive transducer

This page compares Active transducer Vs Passive transducer and mentions difference between Active transducer and Passive transducer.

Active transducer


Definition:
The transducer which does not require any external power source to produce output is called Active transducer. They produce electrical output themselves.


Example:
• Piezoelectric transducers
• Thermocouple
• Photovoltaic cell

Passive transducer


Definition:
Transducer which utilizes power from external source to produce output is called passive transducer.


Example:
• Resistive transducer
• Capacitive transducer
• Inductive transducer

Transducer types

The transducers can be classified as per figure-1 above into following types.
• Active and passive
• Analog and digital
• Primary and secondary
• Transducer and inverse transducer
