Analog Air Quality Sensor for CO2

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 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, and is available with optional temperature output.

Product Applications

• Controlling ventilation in response to accuracy
• ASHRAE 62.1 compliant
• Office buildings, conference rooms, schools, retail stores, etc.
