DESCRIPTION
This ia a micromachined piezoresistive silicon pressure sensor. It
is designed for OEM applications where compatibility with
corrosive media must be maintained. The sensor chip is
mounted on a TO style header, which is resistance welded to a
316 stainless steel package. A 316 stainless steel convoluted
isolation diaphragm is welded to the package, sealing a small
volume of silicone oil between the diaphragm and the sensor
chip. The ISO pressure housing utilizes the oil column to couple
the piezoresistive sensor to the isolation diaphragm. A thickfilm
ceramic compensation board with laser trimmed resistors, and
an additional gain set resistor to normalize pressure sensitivity
are an integral part of the sensor package. A variety of threaded
process fittings are available. Fittings include standards like 1/4
and 1/8 NPT, 1/4 BSP as well as custom process fittings.
