Diaphragm Pressure Gauge
0 likes
China [CN] Diaphragm pressure gauge (chemical seals pressure gauge) is composed of a conventional pressure gauge, connector and a diaphragm seal. This combination enables a general industrial purpose pressure gauge to measure media of strong corrosion, high temperature, and high viscosity, containing suspended matter or crystallizing. Diaphragm pressure gauges are universally used in petrochemical, alkali, and chemical fiber, pharmaceutical, metallurgical, and food industries. We are a China Diaphragm pressure gauge manufacturer, we supply cheap custom diaphragm pressure gauge but still with robust and stable quality. Custom diaphragm seal pressure gauge, such as sanitary pressure gauge, capillary type pressure gauge, flanged pressure gauge, flush mount pressure gauge, high temperature pressure gauge.,etc. welcome to send your drawings or your technical specifications for pressure gauge diaphragm type. We will design for you.
This illustration shows the operating principle of the pressure gauge with diaphragm seal. The diaphragm is deflected by the pressure of medium P, and an equivalent pressure P is generated. With transmitting through working fluid, the pressure P. deflect the elastic element of a pressure measuring instrument which thereafter shows the pressure value.
