BLCR Series

The BLCR Series Basic Sensor 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 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.

This series is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. The output is also ratiometric to the supply voltage and is operable from 1.8 to 3.3 volts DC.
