Diaphragm pressure gauge application status - Database & Sql Blog Articles

In daily industrial production, various pressure gauges are also indispensable as a common measuring instrument. There are many kinds of pressure gauges, there are pointer indication type and digital display type, and the function can also carry remote transmission, and the pressure data can be monitored at the scene, and so on. Today we will talk about the diaphragm pressure gauge.

Diaphragm pressure gauge

When measuring the medium pressure, the principle of action is to set the isolation device on the periphery of the pressure gauge. The pressure of the medium is transmitted to the internal pressure gauge through the sealing fluid and the indicated value is obtained. It is characterized by working in a medium-isolated manner. The diaphragm pressure gauge is mainly composed of the pressure gauge itself and a special isolation device. The diaphragm pressure gauge is a special type of product used in the pressure gauge for measuring specific media. It can measure medium with strong corrosion, high temperature and high viscosity. At present, it is widely used in petroleum, chemical, chemical fiber, pharmaceutical and other places involving the measurement of fluid fluids with special properties. Diaphragm pressure gauges have a wide range of applications in industrial production. Especially in high temperature, high corrosion working environment, diaphragm pressure gauge plays a very important role.

Due to the special isolation device, the material in the medium is prevented from accumulating in the pressure gauge. Therefore, the liquid medium which is easy to crystallize, easy to solidify and has solid particles can be measured by using a diaphragm pressure gauge. However, since the diaphragm pressure gauge achieves pressure transmission through the sealing liquid, there are inevitably some disadvantages. Therefore, the self-expansion of the sealing liquid at high temperature will affect the indication value of the pressure gauge. When the temperature is increased, the pressure felt by the pressure gauge will increase, which is more obvious for the diaphragm pressure gauge with a lower range.

It can adapt to all kinds of harsh measurement environments. It works in isolation from the medium. It also has the characteristics of high precision, wide measuring range, large selection space and diversified internal structure.

The diaphragm is designed to protect the structure inside the pressure gauge and the original from damage, so the diaphragm is definitely suitable for measuring corrosive media and media containing impurities as well as high temperature media.
