Primary transducer Vs Secondary transducer-Difference between Primary transducer and Secondary transducer

This page compares Primary transducer Vs Secondary transducer and mentions difference between Primary transducer and Secondary transducer.

Primary transducer

The transducer which converts physical quantity into mechanical displacement is called primary transducer.
• The force detected by the column in first. Hence it is called primary transducer.
• It is a mechanical device.

• Bourdon Tube
• Diaphragm
• Bellows

Secondary transducer

The transducer which converts mechanical displacement into electrical output is called secondary transducer.
• Output of primary transducer is converted into useful signal by secondary transducer.
• It is an electrical device.


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
