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.
