In the production field, pressure gauges are often used for pressure measurement. In different working occasions, the use requirements and performance requirements for pressure gauges are different, so it is necessary to understand the applicable range of different types of pressure gauges. Among them, ordinary pressure gauges can be used to measure the pressure of liquid, gas or steam that is non-explosive, non-crystalline, non-solidified, and non-corrosive to copper and copper alloys. Operating temperature: -40℃～+70℃.
The shock-resistant pressure gauge with a certain degree of shock resistance can be used in places with severe vibration in some working environments and can withstand the pulsation, impact and sudden unloading of the medium, and the indicator is clear and stable. It is widely used in machinery, petroleum, chemical, metallurgy, mining, electric power and other departments to measure the pressure of non-corrosive media on copper and copper alloys. It has a long service life and is a substitute for ordinary pressure instruments.
All stainless steel pressure gauges are made of stainless steel, which can be used in working environments with corrosive gases, can detect the pressure of more corrosive media, and are widely used in petroleum, chemical, metallurgical and other industries.
The shock-resistant stainless steel pressure gauge meter is also made of stainless steel, which can not only be used in corrosive gas environments, but also can detect the pressure of more corrosive media, and is widely used in petroleum, chemical, metallurgical and other industries. Moreover, it can adapt to severe vibration environments, endure pulsating pressure and impact load, and has a wider range of uses. The operating temperature range of this instrument is -25℃~+70℃.
In addition to these commonly used pressure gauges, there is another instrument that is also widely used today, which is, the diaphragm pressure gauge. This type of instrument adopts an indirect measurement structure, which is suitable for measuring the pressure of liquids, gases or solid media containing granular particles with high viscosity, easy crystallization, high corrosion, and high temperature.
