Product Description WA19 Piezoresistive Pressure Sensor A11 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 applications 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 -- constant current and voltage.Features - Pressure Sensor:1. Low cost OEM2. High stability and accuracy3. Suited for pressure of 0-40Kpa...7Mpa4. Wide compenstation temperature range5. Compatible with 316L, suitable for corrosive media6. Standard mounting size7.
