85BSD Media Isolated Digital Output Pressure

Brand: American Sensor Technologies Inc
The 85BSD is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.

This 14-bit digital output pressure sensor supports I²C and SPI interface protocols in either a 3.3 or 5.0 Vdc supply voltage, and is designed to be weldable or threaded with process fittings. 

The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element. The 85BSD is designed for high performance, low pressure applications. 

A custom ASIC is used for temperature compensation, offset correction, and provides a digital output of 10 to 90% or 5 to 95%. For a similar sensor with O-ring mounting, refer to the 86BSD digital output pressure sensor.
