Uses of diaphragm seal pressure gauges
Measuring low and medium pressure: Diaphragm pressure gauges are often used to measure low to medium pressure ranges, especially for pressure measurement of media such as gas, liquid, and steam.
Adapt to harsh environments: Since the diaphragm of the diaphragm pressure gauge can effectively prevent the erosion of the internal structure by the medium, it is suitable for pressure measurement of corrosive media.
Good sealing: It is often used in places with high sealing requirements to prevent liquid or gas leakage.
Suitable for places with high hygiene requirements: In the food, pharmaceutical, chemical and other industries, diaphragm pressure gauges have good hygiene performance.
