DESCRIPTION
The Model 82 is a 19 mm small profile, media compatible,
piezoresistive silicon pressure sensor packaged in a 316L
stainless steel housing. The Model 82 is designed for O-ring
mounting. The sensing package utilizes silicone oil to transfer
pressure from the 316L stainless steel diaphragm to the sensing
element.
The Model 82 is designed for high performance, low
pressure applications. 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%.
Sensors with threaded pressure fittings, weldable flush
