Capsule manometer

Diaphragm pressure gauge is also called micropressure gauge.

In order to increase the displacement of diaphragm and improve the sensitivity of pressure gauge, two concentric diaphragms are welded together to make a hollow diaphragm, and the diaphragm is used as an elastic sensitive element to measure a miniature pressure gauge called diaphragm pressure gauge.

The difference between diaphragm pressure gauge and diaphragm pressure gauge;

Both pressure gauges have diaphragms. Diaphragm function of diaphragm pressure gauge: It acts as an elastic element.

Diaphragm pressure gauge diaphragm function: only isolation and pressure transmission function.

Working principle of diaphragm pressure gauge:

When the pressure P of the measuring medium acts on the diaphragm, the diaphragm will be deformed, compressing the sealing liquid of the pressure measuring system of the pressure instrument to form the structural indication pressure of the diaphragm pressure gauge with P-△ P. When the stiffness of the diaphragm is small enough, △ P is also small, and the pressure formed by the pressure measuring system of the pressure instrument is close to the pressure of the measuring medium.
