ABSTRACT:
Pressure responsive transducer of the potentiometer type having a resistance corresponding to the applied pressure. The transducer is particularly suited for aircraft use and includes a rigid frame fabricated of sheet metal. A pivotably mounted wiper assembly is operably connected to a pressure responsive bellows assembly and makes electrical contact with a resistive element. The wiper assembly includes a shaft with pivots which are received in trunnions which are carried by arms of the frame.
