Diaphragm Pressure Gauge is Suitable for Low Pressure Measurement

Diaphragm pressure gauges are particularly suitable for the process industry. When the Bourdon tube pressure gauge cannot work normally due to reaching the pressure limit, the diaphragm pressure gauge can be used instead. One of the advantages of the diaphragm pressure gauge is that it can perform low pressure measurements.

The diaphragm pressure gauge can be recognized at a glance because of its special appearance: the bottom of the watch case is equipped with a flange, and an elastic pressure element (diaphragm element) is sandwiched between the flanges. This series of pressure gauges can measure pressures as low as 1.6 kPa and as high as 2.5 MPa (in comparison: the lowest pressure value that can be measured by the Bourdon tube pressure gauge is 60 kPa).

The larger the diaphragm, the smaller the measurable low-pressure value. Refer to the formula: pressure = force / area. DPG can provide two sizes of diaphragms: diaphragms with a range of 0 -1.6 kPa to 0- 25 MPa and a diameter of 134.5 mm and diaphragms with a range of 0 -40 kPa to 0 – 2.5 MPa and a diameter of 76.5 mm.

We can customize the corresponding pressure gauge according to the measured pressure value. We will also launch more professional answers at the same time, please follow us.
