Pneumatic Electric Transducer

Fluid pressure signals are readily converted to electric signals by a transducer body. It has chamber 10 with an elastic diaphragm 12. This is of a plastic material stretched across it so as to be subjected to fluid pressure pulses from inlet conduit 14.

A conductive surface is provided such as by a strip of foil 16 secured to the surface of the diaphragm. It engages an adjustable stationary contact 18.

This is when the diaphragm is stretched by the application of fluid pressure signals. Contact 18 and foil 16 are connected in circuit with voltage source 20 and resistor 22 across which electric signals are derived.
