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

The 85 Flush Mount is designed for O-ring mounting where the diaphragm must not be shrouded by a weld ring or fitting. 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 compensation 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%.
