The Fairchild T7800/7801 Series Transducers provide maximum versatility for precision applications. It converts a DC input signal to a linearly proportional pneumatic output. Its compact size permits use in space restricted areas.
The Fairchild T7800/7801 Series converts a DC input signal to a linear proportional pneumatic output. It includes the Primary Converting Section and the pneumatic Relay Section. The Piezoelectric Ceramic Actuator, in the Primary Converting Section, functions as a Flapper. The Flapper and Nozzle work together to control the signal pressure. The signal pressure that sets the output pressure acts on the Upper Control Diaphragm in the Pneumatic Relay Section. The Lower Control Diaphragm in the Pneumatic Relay Section senses the output pressure.
In the Extended Range units, an additional Relay Section amplifies the output pressure.
