DESCRIPTION
This is a micro machined 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, 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 piezoresisteve
sensor to the isolation diaphragm. A thickfilm ceramic
compensation board with laser trimmed resistors, and
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 as well as custom process fittings. Electrical
options include cable and connector.
