High precision vacuum pressure sensor thin film vacuum gauge CMKS specification 0-1000Pa

VR-208C-510 series intelligent vacuum gauge: Combining the high-precision characteristics of standard capacitive thin film vacuum gauges with the digital functions of modern intelligent instruments, and based on the characteristics of China's industrial environment, a high-precision intelligent vacuum gauge suitable for new energy, new materials, research institutes, aerospace, petrochemical, and fine chemical working conditions has been specially developed. Compared with similar products of foreign brands, it has the characteristics of domestic price and imported quality, and many aspects of product standards can be mutually used to achieve localization; It also has special vacuum gauge products such as high-temperature, corrosion-resistant, explosion-proof, industrial protection, low-power consumption, and space environment types

　　VR-208C-510Series intelligent vacuum gaugeIt is a new type of thin film vacuum gauge with intelligent measurement and control functions. It is a precision digital display and adjustment instrument for vacuum degree, suitable for industrial automation precision measurement and control of various vacuum equipment, such as biomedicine, vacuum freeze-drying, pharmaceuticals and fine chemicals, medical vacuum cold chain technology, vacuum acquisition equipment, multi-stage vacuum units, vacuum drying, vacuum coating, vacuum smelting, vacuum forging heat treatment, vacuum single crystal furnace, optoelectronic industry, aerospace and military vacuum equipment, chemical vacuum distillation, electrical insulation vacuum impregnation equipment, vacuum injection, vacuum oil filter, vacuum pre cooling preservation, vacuum food processing equipment, vacuum environmental protection filtration, purification system, etc. It is also used in laboratories, measuring rooms, etc., with relevant ranges (0.01Pa -200kPa). 0.1 level precision vacuum standard (replacing CNAS) Qualification measurement calibration certificate, etc.

　　VR-208-510Series intelligent vacuum gaugeThe vacuum degree sensor adopts the new generation of foreign capacitor film vacuum measurement technology (high-precision ceramic capacitor film gauge), integrates the research results of intelligent instrument technology, and overcomes the shortcomings of traditional vacuum gauges (thermocouple gauge, resistance gauge, Pirani gauge and other heat conduction vacuum gauges, alloy film gauge, Maxwell gauge, etc.), such as the need for calibration before measurement, large measurement errors, and large drift. The ceramic capacitor gauge has an annual stability of<0.1% and does not require calibration for industrial control within the year; The metrological stability of online continuous measurement of vacuum degree and the reliability and safety of process control have been significantly improved by the instrument;

　　VR-208C-510Series intelligent vacuum gauge,Capacitive thin film vacuum gauge is a type of vacuum gauge that measures absolute and total pressure. Its measurement results directly reflect the changes in vacuum pressure and are only related to pressure, regardless of gas composition (which cannot be achieved by traditional heat conduction vacuum gauges such as resistance gauges, thermocouple gauges, Pirani gauges, etc.). The VR-208 series intelligent vacuum gauge combines the performance of ceramic capacitive thin film vacuum gauge and intelligent measurement and control instrument. It is an upgraded version of traditional vacuum gauge and a powerful tool for high-precision vacuum measurement and control.

In addition, compared with similar foreign thin film vacuum gauge products, this series of products has strong industrial protection performance (its vacuum sensor protection level: IP56, with dust and rain resistance), intrinsic safety explosion-proof (explosion-proof level ExiaICT6) performance, etc. It can also customize chemical vacuum sensors with special requirements based on customer requirements using highly corrosion-resistant and high-temperature resistant tetrafluoroethylene and fluororubber materials. Equipped with PS-115F professional explosion-proof vacuum sensor, its explosion-proof level can reach ExdIIBT6.
