Digital pressure sensor suits hostile environments

The piezoresistive silicon pressure sensor incorporates a custom ASIC for temperature compensation and offset correction. The 14-bit digital output supports both I²C and SPI interface protocols to meet specific application data requirements.

Mountable with an o-ring seal, the 86BSD is easily and securely installed in a number of applications including level control, sealed systems, manifold and barometric pressure measurement as well as submersible depth monitoring and corrosive fluids and gas measurement. Silicone oil accurately transfers the pressure from the 316L stainless steel diaphragm to the sensing element.

Configured in a backside, header-less design, the new sensor is both compact and cost-effective to use. It is available in a pressure range of 1-300psi (0.07-20bar) in either absolute or gage references with an operating temperature from -40 to +125°C.

The unit provides a total error band of up to ±1%Span, which includes calibration errors and temperature effects over the compensated range from -20 to +85°C, as well as an accuracy of ±0.25%Span.

Pricing for an 86BSD is $20 (USD) per unit in quantities of 10,000. Delivery time is dependent upon quantity ordered.
