Differential Pressure Gauges

A Differential Pressure Gauge works on the pressure difference acting on the sensor, bourbon or diaphragm or on both sides ( h. P & l. P ) of a cylinder which gets a displacement that actuates a gear movement or any similar mechanism to an indicating pointer which moves over a dial marked in difference of pressure.
