Thin film vacuum gauge for chemical distillation

Thin film vacuum gauge for chemical distillation (high-precision, corrosion-resistant type)In order to meet the market demand for measuring vacuum degree and pressure in strong acid and alkali atmospheres in chemical and scientific research, our company has developed high-precision and corrosion-resistant ceramic capacitive vacuum degree and pressure sensors and transmitters. The contact part between the sensor and the corrosive gas medium being measured is made of polytetrafluoroethylene material that is corrosion-resistant, high-pressure resistant, and high-temperature resistant. At the same time, the advantages of ceramic capacitive measurement chips are utilized to fill the gap in high-precision measurement and control sensors for highly corrosive gases in China.

Capacitive 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 and not to gas composition. This is something that traditional heat conduction vacuum gauges such as resistance meters, thermocouple meters, Pirani meters, etc. cannot achieve. In addition, the thermocouple wire and resistance wire of traditional vacuum gauges come into direct contact with the measured medium, causing corrosion and contamination, making it impossible to measure stably and even quickly damaged, making it impossible to use in chemical systems. The VR-208 series thin film vacuum gauge uses a ceramic surface to sense vacuum pressure and has excellent corrosion resistance, supplemented by corrosion-resistant materials such as PTFE engineering plastic and 316 stainless steel. Can be applied to precision measurement and control of chemical vacuum equipment.

The VR-208C-510 series thin film vacuum gauge also combines the measurement and control performance of ceramic capacitive thin film vacuum gauges and modern intelligent measurement and control instruments, with multiple measurement and control modes and analog-to-digital communication interfaces. It is an upgraded product of traditional vacuum gauges and a choice for precision vacuum measurement and control under many special working conditions.

The series of products have strong industrial protection performance (with a vacuum sensor protection level of IP56, dust-proof and rainproof), intrinsic safety and explosion-proof (explosion-proof level ExiaICT6) performance, etc. Customized chemical vacuum sensors with special requirements. Equipped with PS-115F professional explosion-proof vacuum sensor, its explosion-proof level can reach ExdIIBT6. These characteristics are not considered by high-precision thin film vacuum gauges abroad.
