Series CDTC Communicating Carbon Dioxide Sensor
NDIR CO2 Sensor, Measures CO2, Temperature, Temperature Set Point, and Override
The Series CDTC Communicating Carbon Dioxide Sensor combines the function of two room sensors into a single, compact housing. Parameters include carbon dioxide, temperature, and temperature set point with override. A 4-wire connection and daisy chaining together reduces installation cost. The RS-485 MAC address is set up using on-board DIP switches. Additional DIP switches are used to select Modbus® RTU or BACnet MS/TP and to limit access to the set up menu. The Series CDTC uses a Single Beam Dual Wavelength Non-Dispersive Infrared (NDIR) sensor to measure the carbon dioxide level allowing for installations that will be occupied 24 hours per day. For improved accuracy, the transmitter can be field calibrated to the environmental conditions of the installation. The barometric pressure can be programmed to correct for altitude. Optional integral and remote displays are available to display temperature, or temperature set point instead of CO2.
