FST800-216 high-temperature 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 chamber is made of imported 17-4PH stainless steel in an integrated way without welding seams or O-rings and free of leakage troubles. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are installed inside the transmitter. The temperature compensation scope is from -40°C-150°C. 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.
