Circuit Board Assembly for TX7850 I/P Transducer

Brand: Fairchild Industrial Products

The Model TXI7850 Transducer is an electronically controlled pressure sensitive device that converts a current signal to a pneumatic output. 

This device is composed of the Primary Converting Section and the Relay Section. The Piezoelectric ceramic disk in the Primary Section functions as a flapper. The flapper and the nozzle work together to control the signal pressure in the Relay Section.

The signal pressure acts on a diaphragm assembly that controls the pressure in the output chamber.
