86BSD - digital pressure sensor with stainless steel membrane 16 mm by AMSYS

86BSD – digital pressure sensor with stainless steel membrane 16 mm

The 86BSD 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, may come in a 3.3 or 5.0Vdc supply voltage and is designed for o-ring mounting.

This small 16mm, ASIC calibrated pirezoresistive silicon pressure sensor is designed to be mountable with an o-ring seal for high performance, low pressure applications. It utilizes silicone oil to transfer pressure from its 316L stainless steel diaphragm to its sensing element.

The 86BSD is configured in a backside, header-less design with a pressure range of 1 – 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 fluids and gas measurement systems, OEM equipment, sealed systems, manifold pressure measurement, barometric pressure measurement and submersible depth monitoring.
