This multi-functional CO2 and temperature transmitter uses an advanced CO2 sensing technology. The second-generation, silicon-based CARBOCAP® sensor provides stability and reliability.

The CARBOCAP sensor operates in accordance with the single-beam, dual-wavelength method. This patented sensor has unique reference measurement capabilities, offering excellent stability over 5 years in typical HVAC applications.

The monolithic Fabry-Perot Interferometer (FPI) chip uses the optical, mechanical, and electronic properties of silicon at the same time.

The transmitter is factory set to measure CO2 levels up to 2,000 ppm. It requires a Class 2, 24 VDC/VAC power source and generates an output signal proportional to the CO2 level detected. One simple wire to a screw terminal and a jumper on the Printed Circuit Board (PCB) combine to select the analog output signal from the following options:

  • 0 to 5 V
  • 0 to 10 V (default)

This transmitter includes an analog temperature output, linear from 0 to 10 VDC for 23 to 131°F(-5 to 55°C), for applications requiring both CO2 and temperature monitoring.

Important: The CD-WAx-00-2 CO2 and Temperature Transmitter is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the transmitter could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the transmitter.
