Product Description

BLC Series Low Pressure Compact Sensors General Description
The BLC Series Basic Low Pressure Compact 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 supply voltage and is operable from 0.9 to 1.8 volts DC. 

BLC Series Low Pressure Compact Sensors Features
• 0 to 1 inH2O to 0 to 30 inH2O and 15 PSIA Pressure Ranges
• uPower Low Supply Voltage (0.9V to 1.8V)
• 0.1% Linearity Typical
• Improved Front to Back Linearity
• Less Position Sensitivity
• Improved Warm-Up Shift Distribution
• Parylene Coating Available Upon Request
