This multifunctional 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 five years in typical HVAC applications.
The CO2 transmitter is factory-set to measure CO2 levels up to 2,000 ppm. It requires a Class 2, 24 VAC/VDC power source and generates an output signal proportional to the CO2 level detected. One simple wire to a screw terminal on the Printed Circuit Board (PCB) selects the analog output signal from the following options:
- 0 to 10 V
- 4 to 20 mA
The multifunctional device also features a connection to an internal platinum temperature sensor (Pt1000 RTD). This temperature sensor has a range of 32 to 122°F, which allows for accurate temperature measurement in many common HVAC applications.
