A vacuum pressure gauge is used to measure pressures below atmospheric pressure based on atmospheric pressure. It is suitable for measuring vacuum pressures of liquids and gases that are non-explosive, non-crystalline, and non-corrosive to copper and copper alloys.
It is widely used in industries such as gas transportation, measuring the pressure of various non-corrosive, non-explosive, non-crystalline liquids, gases, and vapors, and industries including industrial automation, petroleum pipeline, water conservancy, hydropower, railway transportation, smart buildings, production automation, aerospace, military industry, petrochemical industry, oil wells, power generation, ships, machine tools, gas supply pipelines, vacuum equipment and many others. It is precisely because of its wide application in various industries that pressure gauge suppliers have introduced a variety of vacuum pressure gauges.
A vacuum pressure gauge uses a bourdon tube, bellows, or corrugated tube to deform the pressure-sensitive component, and then the deformation pressure is transmitted to the pointer through conversion to make the pointer rotate.
Its composition is also very simple, consisting of a pointer, a glass panel, and an overflow. The role of the overflow is that if the pressure in the device is too high, in order to prevent the glass panel from exploding and threatening our personal safety, the excess pressure will open the overflow to release the gas in the dial.
According to different application objects and fields, they can be divided into standard normal type, h heat-resistant type, m common type for steam, v seismic-resistant type, mv steam durable type, and hv heat-resistant seismic-resistant type. Before installation, the main body of the vacuum pressure gauge must not come into contact with oil or water. If accidentally touched, immediately use absorbent paper to dry the water or oil, otherwise, it will affect the display effect of the dial. Intelligent pressure gauge, which incorporates advanced features such as data logging, trend analysis, and Bluetooth connectivity, is also becoming increasingly popular in modern vacuum systems. Choosing the right type of vacuum pressure gauge requires consideration of factors such as vacuum range, compatibility with the process medium, and reliability. Ultimately, selecting the right type of vacuum pressure gauge is essential to ensure optimal performance and productivity in vacuum applications.
High equipment stability, fast measurement speed, and high precision.
There are no high-temperature components inside the vacuum pressure gauge, so it will never be melted by high-temperature steam or oil.
Its structure is very stable, not easy to deform, and easy to transport and install.
The measurement value is not affected by the type, density, temperature, and other conditions of the medium.
Vacuum gauge: based on atmospheric pressure, used to measure pressures below atmospheric pressure.
Ordinary pressure gauge: refers to a pressure gauge that uses an elastic element as the sensitive element to measure and indicate pressures higher than the ambient pressure.
Vacuum gauge: vacuum gauge and pressure gauge are used to measure liquids or gases that have no corrosive effect on steel, copper, or copper alloys and no explosion danger.
Ordinary pressure gauge: can be seen everywhere in fields such as heating pipe network, oil and gas transportation, water and gas supply systems, automobile repair shops, and sales outlets. Especially in industrial process control and technical measurement processes, as the mechanical pressure gauge's elastic sensitive element has characteristics such as high mechanical strength and easy production, mechanical pressure gauges are becoming more and more widely used.
