DESCRIPTION
The Model 82 Low Pressure is a 19 mm small profile, media compatible, piezoresistive silicon pressure
sensor packaged in a 316L stainless steel housing. The Model 82 Low Pressure is designed for o-ring mounting
and 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 Model 82 UltraStable™ datasheet for information on products with operating
pressures greater than 5 psi.
