89U Media Isolated mV Output Pressure Sensor

Brand: American Sensor Technologies Inc

The 89 uncompensated is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.

The 89 uncompensated 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 uncompensated 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.
