This cost-effective sensor monitors Carbon Dioxide and temperature using stable dual-beam NDIR technology. It is designed for standard commercial applications where reliability and budget are both priorities.
This cost-effective sensor monitors Carbon Dioxide and temperature using stable dual-beam NDIR technology. It is designed for standard commercial applications where reliability and budget are both priorities.
The CWE2 Series of air quality sensors for living space are for use with BAS controllers designed to accept 4 to 20mA, 0 to 5 Vdc or 0 to 10 Vdc outputs. These sensors measure CO2 levels using a dual-beam, non-dispersive infrared (NDIR) technology. The CWE2D measures temperature as well. The CWE2 Series Economy sensor has an accuracy of ±30 ppm ±3% of measured value, features 2-wire 4 to 20mA and 3-wire voltage outputs.
