Description:
Differential Pressure Gauges are intended for measuring the pressure differential existing across two media or two parts of a system. As per the application demand, all common pressure elements are used. The pressure element separates the two pressurised media and the resulting deflection is 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 both the pressures is not usually indicated. Elastic pressure gauges indicate the relative difference between the pressure of the medium and the surrounding atmosphere. The construction is simple & robust and does not require any additional source of energy for its operation.
