Analyze the principle and application of diaphragm pressure gauge

by:Sure     2021-08-01
In daily industrial production, various pressure gauges are also indispensable as a common measuring instrument. There are many types of pressure gauges, pointer indication type and digital display type, and the function can also be equipped with remote transmission, and the pressure data can be monitored when not on site, and so on. Today we will talk about the diaphragm pressure gauge. When the diaphragm pressure gauge measures the pressure of the medium, its function principle is to isolate all kinds of pressure gauges as a common measuring instrument in the daily industrial production. There are many types of pressure gauges, pointer indication type and digital display type, and the function can also be equipped with remote transmission, and the pressure data can be monitored when not on site, and so on. Today we will talk about the diaphragm pressure gauge.   When the diaphragm pressure gauge measures the pressure of the medium, its working principle is to set the isolating device on the periphery of the pressure gauge. The pressure of the medium will be transmitted to the internal pressure gauge through the sealing liquid, and the indicated value will be obtained. Its characteristic is to use the medium isolation method to work. The diaphragm pressure gauge is mainly composed of the pressure gauge itself and a special isolation device. The diaphragm pressure gauge is a special kind of product used to measure specific media in the pressure gauge. It can measure the medium with strong corrosion, high temperature and high viscosity.   At present, it is widely used in petroleum, chemical, chemical fiber, pharmaceutical and other places that involve the measurement of fluid media with special properties. Diaphragm pressure gauges have a wide range of applications in the field of industrial production. Especially in the working environment of high temperature and high corrosion, the diaphragm pressure gauge plays an extremely important role.   Diaphragm pressure gauge is equipped with a special isolation device, which prevents the substance in the medium from accumulating in the pressure gauge. Therefore, liquid media that is easy to crystallize, solidify, and have solid particles can be measured by the diaphragm pressure gauge.   However, because the diaphragm pressure gauge uses a sealing fluid to achieve pressure transmission, there are inevitably some shortcomings. Therefore, the self-expansion of the sealing fluid at high temperatures will affect the indication value of the pressure gauge. When the temperature increases, the pressure experienced by the pressure gauge will increase. This is more obvious for the diaphragm pressure gauge with a low range.   Diaphragm pressure gauge can adapt to various harsh measurement environments. It works in isolation from the medium. It also has the characteristics of high accuracy, wide measurement range, large selection space, and diversified internal structure. The diaphragm in the diaphragm pressure gauge is to protect the internal structure and original parts of the pressure gauge from damage, so the diaphragm with the diaphragm must be suitable for measuring corrosive media and media containing impurities and high temperature media.
