Diaphragm pressure gauge
Diaphragm pressure gauge introduction:
Diaphragm pressure gauge is suitable for measuring medium pressure with strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, solid float, and must avoid measuring medium from directly entering universal pressure gauge and preventing sediment from accumulating and easy to clean. The diaphragm table is composed of a diaphragm isolator and a universal pressure meter. Diaphragm pressure gauges and equipment connection methods are mainly threaded connection and flange connection and sanitary clamp type. Diaphragm table is mainly used in petrochemical, soda, chemical fiber, dyeing, pharmaceutical, food and alkali and other industrial sectors in the production process For measuring fluid medium pressure.
Diaphragm pressure gauge structure principle:
When the pressure P of the measuring medium acts on the diaphragm, the diaphragm is deformed, and the sealing liquid of the pressure meter pressure measuring system is compressed to make the pressure of P-ΔP. When the rigidity of the diaphragm is small enough, the ΔP is also small, and the pressure gauge pressure measuring system forms a pressure close to the pressure of the measuring medium.

For low-pressure gauges, the effect is even more pronounced. Generally, the pressure error of the pressure part is not more than 0.1%/°C. Therefore, the total temperature effect of the diaphragm pressure meter is generally the sum of the temperature influence of the general-purpose instrument and the temperature influence of the pressure part of the diaphragm device.
