All Sensors has announced a brand new low pressure sensor, the BLCR Series. This new device series offers design engineers excellent performance over pressure ranges of ±1 inH2O through ±30 inH2O. The BLCR Series is based on a dual die reference technology to reduce all output offset or common mode errors. It also incorporates All Sensors’ CoBeam2 TM Technology to reduce the overall supply voltage while maintaining comparable output levels to traditional equivalent basic sensing elements. This lower supply voltage gives rise to improved warm-up shift while the CoBeam2 TM Technology itself reduces package stress susceptibility resulting in improved overall long term stability. The technology also vastly improves position sensitivity to nearly immeasurable levels.  This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. The compact size of this series will provide excellent opportunities for small mobile devices. The basic output is also ratiometric to the supply voltage and is operable from 1.8 to 3.3 volts DC, which are ideal for battery applications. Devices are available in 1, 5, 10, 20, 30 inH2O (250, 1.25k, 2.5k, 5k, 7.5k Pa) differential ranges.

Ideal applications for this device include:

medical devices, pneumatic controls, instrumentation, environmental controls.
