It also 2 incorporates All Sensors CoBeam Technology to reduce the overall supply voltage while maintaining comparable output levels to 2 traditional equivalent basic sensing elements. This lower supply voltage gives rise to improved warm-up shift while the CoBeam 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 ratio - metric to the supply voltage and is operable from 1.8 to 3.3 volts DC.
