Request Information Favorite
The 86 Vacuum Gauge is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.

The 86 vacuum gauge is designed for O-ring mounting and 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 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%.

  • -40ºC to 125ºC Operating Temperature Range
  • Up to ±0.1% Pressure Non Linearity
  • 1.0% Interchangeable Span (provided by gain set resistor)
