It is also indispensable to switch all kinds of pressure gauges into a common measuring instrument in daily industrial production. 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, Shanghai Automation Instrumentation Factory No. 4 (www.XINYIYB.COM) will talk about diaphragm pressure gauges. When measuring the pressure of the medium, the diaphragm pressure gauge works by placing 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 a digital pressure gauge itself and a special isolation device.
Membrane pressure gauges are a special class of products used in pressure gauges to measure 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. Diaphragm pressure gauges are equipped with special isolation devices to prevent substances in the medium from accumulating in the pressure gauge. Therefore, liquid media that are easy to crystallize, solidify, and have solid particles can be measured 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.
The diaphragm pressure gauge can adapt to various harsh measuring environments. It works in isolation from the medium, and has the characteristics of high precision, wide measuring range, large selection space and diversified internal structure. The diaphragm in the diaphragm pressure gauge is 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 and high temperature media.
