Transmetteur de pression à sécurité intrinsèque

FST800-214 intrinsic-safety pressure transmitter is a silicon MEMS strain gauge sensor which is glass bonded to a stainless steel diaphragm. It avoids influences on product caused by temperature, humidity, mechanical fatigue and medium, thus to improve its longterm stability in the industrial environment. Its pressure sensitive elements are made of imported 17-4PH stainless steel in an integrated way and a high-performance intrinsic-safety explosion-proof circuit identified by relevant state authorities is installed inside with the explosion grade of ExdⅡCT6. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are installed inside the transmitter, and the transmitter is featured with the strong interference resistance, wide working temperature scope, and longterm stability, etc. The series products provide several optional pressure connections and electric connections for customers.
