Abstract
A piston-type differential pressure gauge provides an electronic output for remote monitoring. A linear potentiometer, in communication with a magnetic portion of the piston of the gauge, tracks the location of the piston. Resistance change in the potentiometer can be used by an electronic circuit to provide the electronic output of the differential pressure remotely to a data acquisition system or control electronics.
