Product Description

BLV Series Low Voltage Pressure Sensors General Description
The BLV Series Basic Sensor is based on All Sensors' CoBeam 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 CoBeam Technology itself reduces package stress susceptibility resulting in improved overall long term stability. The technology also vastly 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 output is also ratiometric to the suply voltage and is operable from 0.9 to 1.8 volts DC.

Performance Characteristics for BLV Series Low Voltage Pressure Sensors

All parameters are measured at 1.8 volt excitation and room temperature unless otherwise specified . Pressure measurements are with positive pressure applied to port B (the only port for the single port configuration ).
