Differential pressure gauges measure difference in two pressures
Cameron Instruments offers the Orange Research differential pressure gauges, designed to measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressures while completely isolating the differential pressure gauge function from the pressure chamber without the use of mechanical seals. They can indicate small values of differential pressure even when used at high line pressures. The gauges are supplied with reed switches or relays and transmitter options are available to transmit signals.
