86BSD Digital Barometric Pressure Transducer With Stainless Housing
Pressure Medium: Air/Gas, Harsh & Liquid Environments
Sensor Type: Absolute
Supply Voltage: Under 5V, 5V
Output Signal: Digital
Pressure Range: 4” H2O to 3 psi

The 86BSD is a small profile, media compatible, piezoresistive silicon pressure sensors packaged in a 316L stainless steel housing. This digital output pressure sensor supports I2C and SPI interface protocols, may come in a 3.3 or 5.0 VDC supply voltage and is designed for O-ring mounting. 

The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element.

The 86BSD is designed for high performance, low pressure applications. A custom ASIC is used for temperature compensation, offset correction and provides a digital output of 10-90% or 5-95%. Various pressure ranges up to 300 psi.
