FST800-12 Constant Current Diffused Silicon Oil filled Piezoresistive Pressure Sensor

Product Description
Product Description
FST800-12 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.
FST800-12 Constant Current Diffused Silicon Oil filled Piezoresistive Pressure Sensor are 0-10Mpa...70Mpa high range sealed gauge sensors. It is designed for O-ring mounting for the applications where compatibility with corrosive media is required.
Each sensor was strictly temperature compensated for both zero and span
