The CO2 Duct Probe with Analog Temperature Sensor uses a completely new CO2 sensing technology. The 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 both time and temperature. 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:
