87N Compensated

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 in a 316L stainless steel package, sealing a small volume of silicon 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 thick-film 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.
