Product Description
FST800-5500 series are based on piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. The sensing package utilizes silicon oil to transfer pressure from the 316L diaphragm to the sensing element. It is designed for o-ring mounting for the application where compatibility with corrosive media is required. Each sensor was strictly temperature compensated for both zero and span. There are two options of excitation power--current and voltage
