Product Specification

BLCR Series Low Voltage Pressure Sensors General Description
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' CoBeam 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 whilte 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 ratiometric to the supply voltage and is operable from 1.8 to 3.3 volts DC.

Performance Characteristics for BLCR Series Low Voltage Pressure Sensors
All parameters are measured at 3.3 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 ).
