Part No. CDT-2E4E
Product Overview
The Dwyer Series CDT Carbon Dioxide Transmitters accurately monitor CO₂ concentration and temperature in indoor environments to support ventilation control and energy-saving strategies. The CDT-2E4E is a wall-mount model with a European housing, a 0-2000 ppm CO₂ range and a Pt1000 Ω RTD temperature output.
A single-beam, dual-wavelength NDIR sensor automatically compensates for light-source aging effects in both occupied and unoccupied buildings. The transmitter provides digital barometric pressure adjustment and field calibration capability for accurate measurement.
The CO₂ output is universal and can be selected as 4-20 mA, 0-5 VDC or 0-10 VDC to match the connected controller. Push buttons provide access to the menu structure, while an internal DIP switch can lock the menu to help prevent unwanted changes. Backplate electrical connections simplify installation.
