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.
