Understanding Double Diaphragm Differential Pressure Gauge Products

In the realm of industrial measurement and control, precision is paramount. Among the various instruments used to measure pressure differences in fluids, the double diaphragm differential pressure gauge stands out for its reliability and accuracy. This specialized device is crucial in applications where accurate pressure measurements are essential, such as in chemical processing, oil and gas production, and water treatment facilities.

What is a Double Diaphragm Differential Pressure Gauge?

A double diaphragm differential pressure gauge is designed to measure the pressure difference between two points in a system. The fundamental working principle is based on the deflection of two diaphragms, separated by a specific distance. When pressure is applied to one side of the gauge, it causes one diaphragm to flex, and the resulting displacement is converted into a pressure reading that reflects the difference between the two input pressures.

These gauges consist of two pressure ports, allowing for the comparison of pressures from different points in a system. The dual diaphragm design provides several advantages, including enhanced resistance to over-pressure conditions and the ability to handle more aggressive media without damage.
