New low-pressure sensors, called the BLC Series, work over pressure ranges of ±1 in. H2O through ±30 in. H2O 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 improves position sensitivity compared to conventional single die devices.
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 makes it a good candidate for small mobile devices. The basic output is also ratiometric to the supply voltage and is operable from 0.9 to 1.8 Vdc, convenient for battery applications. Devices are
available in 1, 5, 10, 20, 30-in. H2O (250, 1.25k, 2.5k, 5k, 7.5 k Pa) differential and 15 psi (103 k Pa) absolute pressure ranges.
