Diaphragm Pressure Gauge Working Principle
When the pressure P of the measuring medium acts on the diaphragm type pressure gauges, the diaphragm deforms and compresses the sealing liquid of the pressure measuring system of the pressure instrument to form a pressure of P-Delta P. When the rigidity of the diaphragm seal type pressure gauge is small enough, Delta P is also very small, and the pressure formed by the pressure measuring system of the pressure meter is close to the pressure of the measuring medium.
What is Diaphragm Seal Type Pressure Gauge?
The diaphragm seal type pressure gauge is composed of a diaphragm isolator and a universal pressure gauge to form a system of diaphragm pressure gauge. The connection between the gauge diaphragm seal and the equipment mainly includes threaded connection, flange connection, and sanitary clamp type. The diaphragm seal type pressure gauge working is suitable for measuring the pressure of the medium with strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, and solid floating matter. It is necessary to prevent the measuring medium from directly entering the general pressure instrument and prevent the accumulation of sediment and easy to clean.
FAQ of Diaphragm Vacuum Gauge
QWhat is the difference between gauge diaphragm seal and other pressure gauges?
When the measured medium is very corrosive (such as hydrochloric acid, wet chlorine, ferric chloride), has a high viscosity (such as latex), easy to crystallize (such as salt water), easy to solidify (such as hot asphalt), there is a solid floating matter (such as sewage), SUS316 stainless steel pipe will also be corroded by hydrochloric acid. The floating matter in asphalt and sewage will quickly block the pressure guide hole of the pressure gauge, and make the meter lose its function. Diaphragm type pressure gauge can solve these problems. People can choose different corrosion-resistant diaphragm materials according to different strong corrosive media to play a role in corrosion protection.
QWhat situation dose a diaphragm vacuum pressure gauge work?
The diaphragm pressure gauge is mainly used in petroleum, chemical, chemical fiber, dyeing, pharmacy, soda food and other industrial sectors.
QWhat is the diaphragm pressure gauge price ?
As a diaphragm seal manufacturer, we can provide users with a good diaphragm seal type pressure gauge selection program and provide preferential products while at a preferential price. At the same time, according to user needs, the prices differ in accord with the design and manufacture of special purpose pressure gauge products.
As a pressure gauges factory, we will do our best to meet all the needs of customers.
