Gas Piston pressure calibrator nitrogen dead weight tester with high accuracy

Description Gas Piston pressure calibrator nitrogen dead weight tester with high accuracy

Gas piston manometer is a measuring instrument that uses the principle of hydrostatic balance (that is, the fluid pressure acting on the effective area of ​​the piston is balanced with the gravity it loads) to measure pressure. In addition, the corresponding gas source should be equipped. The gas piston manometer is a high-accuracy pressure standard. It uses gas as the working medium to measure and calibrate gauge pressure, absolute pressure, vacuum pressure (negative pressure), etc. The material of the piston rod of the piston manometer is stainless steel and the material of the piston barrel is tungsten carbide. So as to ensure that the piston has the characteristics of non-rust, wear resistance and long service life. Compared with the piston manometer using gas as the working medium and the piston manometer using liquid as the working medium, due to the different working medium they use, the gas piston manometer has a long rotation duration, high sensitivity and good repeatability. The data is accurate and reliable. Piston pressure gauges have been widely recognized and applied by thousands of units in metallurgy, petroleum, chemical industry, electric power, metering, railway, engineering and other industries.
