All Sensors DS-0275 Rev A
The BLV Series Basic Sensor is based on All Sensors’ CoBeam2 TM Technology. The device provides a high output signal at a low
operating voltage and reduces 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 CoBeam2 Technology itself reduces
package stress susceptibility resulting in improved overall long term stability. The technology also vastly improves position sensitiv-
ity compared to conventional single die devices.
This series is intended for use with non-corrosive, non-ionic working fl uids such as air, dry gases and the like. The output is also
ratiometric to the suply voltage and is operable from 0.9 to 1.8 volts DC.
