Differential Pressure Gauges

Product Description

These gauges are intended for measuring the pressure differential existing across two media or two parts of a system. All common pressure elements are used, as the application demands. The pressure element separates the two pressurised media, and deflects proportional to the difference in pressures between the media, irrespective of the absolute pressures applied. This deflection is converted into the rotation of a concentric pointer on a dial, similar to regular pressure gauges. The absolute value of either of the pressures is not usually indicated.
