DIFFERENTIAL PRESSURE Selection Guide

Gauges, Switches and Transmitters

 

Orange Research differential pressure gauges are 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 patented magnetic movement allows the simultaneous sensing of both pressures while completely isolating the gauge function from the pressure chamber without the use of mechanical seals.
