82VC Media Isolated mV Output Pressure Sensor
Brand: American Sensor Technologies IncThe 82 Vacuum Gauge is a 19 mm small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.
The 82 vacuum gauge can be configured for O-ring mounting or threaded process fittings and is designed for OEM applications where compatibility with corrosive media is required.
The sensing package utilizes silicone 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%. Please refer to the 82 uncompensated, compensated and constant voltage datasheets for more information on different features of the 82.
