Introduction:

AC16 oil filled sensor 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.
AC16 oil filled sensor series are 0-10Mpa…70Mpa high range sealed gauge sensors. The pressure sensor 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.

Features:

* High stability,High accuracy
* For high pressure range(0-10Mpa…70Mpa)
* Wide compensation temp.
* Compatible with corrosive media
* Standard mounting size
* Millivolt output

Applications:

* Process control
* Fresh and waste water measurements
* Pressure transmitters
