FST800-401 pressure transmitter applied in the engineering machinery industry is a silicon MEMS strain gauge sensor which is glass bonded to a stainless steel diaphragm. It is designed by aiming at the hydraulic application for serious medium problems (e.g. air pocket, liquid hammer or pressure peak value) in the heavy industry. Its pressure chamber is made of 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 and the transmitter is featured with the resistance against impact, overload, shock & erosion, the wide working temperature scope and the longterm stability, etc. The series products provide several optional pressure connections and electric connections for customers.
