AC12 flush diaphragm pressure sensor with fitting 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.
The sensor was welded in front end of a fitting (M20X1.5 or G1/2 made by Stainless Steel 304).
Each sensor was strictly temperature compensated for both zero and span.

Remark:
1. Best fit straight line
2. Measured at vacuum for absolute (A), ambient for gage (G)
3. Maximum temperature range for product with standard cable is -20°C to +105°C
4. Over the compensated temperature range with respect to 25°C
5. Load resistance to reduce measurement errors due to output loading
6. Between case and sensing element
