Delivery time:Delivery time on request
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 5.0Vdc supply voltage.
With a diaphragm of just 13mm in diameter, this ASIC calibrated piezoresistive silicon pressure sensor is designed to be weldable or threaded with process fittings for high performance, low pressure applications. It utilizes silicone oil to transfer pressure from its 316L stainless steel diaphragm to its sensing element.
The 85BSD is configured in a backside, header-less design with a pressure range between 0-5 and 0-300psi in either absolute or gage reference type. Operating from -40°C to +125°C, it features both pressure and temperature read-out capabilities.
This backside digital output pressure sensor can be used for various applications such as: level controls, tank level measurement, corrosive liquid or gas measurement systems, OEM equipment, sealed systems, manifold pressure measurement, barometric pressure measurement and submersible depth monitoring.
