Product Description

WA19 Piezoresistive Pressure Sensor
      WA19 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 -- current and voltage
 

Features - Pressure Sensor:

1.  High stability and high accuracy
2.  Low cost OEM
3.  Suited for pressure range: 0-40Kpa-7Mpa
4.  Wide temperature compensation range: total error <1%
5.  Measurable of corrosive media ( media compatible with 316L)
6.  Standard mounting size
7.   Typical output:0-100mV
