Measurement Specialties has released to production its new 14-bit 85BSD media isolated digital output pressure sensor. With a diaphragm of just 13mm in diameter, this ASIC calibrated pirezoresistive 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. It is one of the first standalone pressure components of its kind in the market.
The 85BSD is configured in a backside, header-less design with a pressure range of 5 – 300psi in either absolute or gage reference type. Operating from -40°C to +125°C, it features both pressure and temperature read-out capabilities, ±0.25% accuracy, ±1.0 TEB (Total Error Band) and provides a digital output of 10~90% or 5~95% in I2C or SPI interface protocols. Optional configurations include a supply voltage of 3.3 or 5.0Vdc, pads or a cable/connector and a low power option.
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. Please contact our team of experienced engineers for further customizability of this pressure sensor for your specific application needs.
