89C Media Isolated mV Output Pressure Sensor

Brand: American Sensor Technologies Inc
The 89 compensated is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.

The 89 compensated features 5/16"- 32 UNEF threads and can be welded in place. It can also be packaged in a variety of threaded fittings such as 1/4" and 1/8" NPT, 1/4" BSP as well as custom process fittings. The 89 compensated is designed for high pressure OEM applications where compatibility with corrosive media is required. 

The sensing package utilizes silicon oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element. A ceramic substrate is attached to the package that contains laser trimmed resistors for temperature compensated and offset correction. An additional laser trimmed resistor is included which can be used to adjust an external differential amplifier and provide span interchangeability to within ±1%.
