New Basic Low Pressure, Compact Sensor

All Sensors » BLC

All Sensors Corporation of Morgan Hill, California has announced a brand new low pressure sensor, the BLC Series. This new device series offers design engineers excellent performance over pressure ranges of ±1 inH2O through ±30 inH2O and 15 PSIA. The BLC Series basic low pressure compact sensor is based on All Sensors’ CoBeam2 Technology. The devices provide a high output signal at a low operating voltage maintaining comparable output levels to traditional equivalent basic sensing elements. This lower supply voltage gives rise to improved warm-up shift while the CoBeam2 Technology itself reduces package stress susceptibility, resulting in improved overall long term stability. The technology also vastly improves position sensitivity compared to conventional single die devices.

All Sensors - BLC

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 0.9 to 1.8 volts DC, ideal for battery applications. Devices are available in 1, 5, 10, 20, 30 inH2O (250, 1.25k, 2.5k, 5k, 7.5k Pa) differential and 15 psi (103k Pa) absolute pressure ranges.
