The BLVR 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 CoBeam
2 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
CoBeam
2
Technology itself reduces package stress susceptibility resulting in improved overall long term stability. The technology
also vastly improves position sensitivity to nearly unmeasurable levels.
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 suply voltage and is operable from 1.8 to 3.3 volts DC.
