Overview
The temperature compensated pressure sensor model 87 features low power consumption and corrosive media compatibility.
The compensated model 87 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.
