Deskripsi Produk

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 OEM
2. High stability and accuracy
3. Suited for pressure of 0-40Kpa...7Mpa
4. Wide compenstation temperature range
5. Compatible with 316L, suitable for corrosive media
6. Standard mounting size
7. Typical output: 0-100mV
