FST800-502 pressure transmitter applied in the refrigeration & compressor industry 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, free of leakage troubles. 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 temperature compensation scope and flexible & various output forms, etc. The series products provide several optional
pressure connectors and electric output forms for customers.
