Explosion proof pressure transmitter
11 month agoHigh-temperature diffusing Silicon pressure transmitter uses high-precision and high-stability high-temperature pressure sensor components of international famous companies. It is a kind of pressure sensor that uses high-temperature resistant pressure core or sapphire core as pressure measuring material. Through high-reliability amplification circuit and precise temperature compensation, it converts the absolute pressure or gauge pressure of the tested medium into standard electrical signals such as 4~20mA,0~5VDC,0 ~ 10VDC and 1 ~ 5VDC. High-quality sensors, fully sealed welding packaging technology and perfect assembly process ensure the excellent quality and abnormal performance of the product. This product has a variety of interface forms and a variety of lead modes, which can meet the needs of customers to a great extent and is suitable for matching with various measurement and control equipment in high temperature industrial environment. It is also widely used in industry, collecting pressure signals in the pipeline pressure measuring parts of some high temperature steam and high temperature fluid.
Application Scope of high temperature diffused silicon pressure transmitter:
It is applied to water plants, oil refineries, sewage treatment plants, building materials, light industry, machinery and other industrial fields to measure the pressure of liquid, gas and vapor.
