CK-02X Duct sensor
The transmitter is designed to measure the concentration of carbon dioxide in the ventilation duct. It designed to be mounted on ducts.
ABCLogic™ automatic calibration method eliminates the possibility of zero point drift. Output can be controlled according to the value of one measured parameter or all parameters. The lower CO2 limit for the control output is set to 400 PPM by default. This means that the control output will transmit a minimum signal (0V or 2V-depending on the selected sensor configuration) for a value of 400 PPM. For the max limit, three values can be chosen: 1000 PPM (default), 1200 PPM and 1400 PPM. The sensor can also be used to transmit signals to the BMS system via 0/2-10V analogue signals. The controller settings can be changed using the configuration tool.
The transmitter can also be used to transmit signals to the BMS system via 0-10V analogue signals. Using internal sensor not only CO2, but also temperature can be monitored. In addition, the transmitter has the ability to measure humidity in the range from 0% to 100% rH.
