Request Information Favorite
The 85 Vacuum Uncompensated pressure sensor is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.

The 85 vacuum uncompensated pressure sensor is offered in a weldable package or with a variety of threaded fittings such as 1/4 and 1/8 NPT, 1/4 BSP as well as other custom process fittings. The 85 uncompensated is designed for 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. Please refer to the 85 compensated and constant voltage datasheets for more information on different features of the 85.
