Part No. CDT-2E44
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 applications. The CDT-2E44 is a wall-mount European housing model with a 0-2000 ppm CO₂ range and an analog temperature output.
A single-beam, dual-wavelength NDIR sensor automatically compensates for light-source aging effects in occupied and unoccupied buildings. The transmitter includes digital barometric pressure adjustment and field calibration capability. Its universal CO₂ output can be configured for 4-20 mA, 0-5 VDC or 0-10 VDC to suit 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. The backplate electrical connection simplifies installation.
The CDT-2E44-LCD is the same transmitter with an integral LCD display.

How to Specify & Commission It
- Confirm the 0-2000 ppm CO₂ range, analog temperature output and European wall-mount housing are suitable for the application.
- Mount the transmitter according to the installation requirements.
- Wire the power supply and select the required 4-20 mA, 0-5 VDC or 0-10 VDC CO₂ output.
- Connect the analog temperature output to the appropriate controller input.
- Set the barometric pressure and perform field calibration if required.
- Configure the menu and lock it with the internal DIP switch if required.
- Verify CO₂ and temperature readings at the connected controller.
Frequently Asked Questions
What does the CDT-2E44 measure?
It measures CO₂ from 0-2000 ppm and provides an analog temperature output.
What CO₂ outputs are available?
The universal CO₂ output can be configured for 4-20 mA, 0-5 VDC or 0-10 VDC.
How accurate is the CDT-2E44?
CO₂ accuracy is ±40 ppm + 3% of reading at 2000 ppm. Temperature accuracy is ±1°C at 25°C.
What sensor technology is used?
It uses a single-beam, dual-wavelength NDIR sensor with a 15-year life expectancy.
Does the CDT-2E44 have an LCD display?
No. The CDT-2E44 does not have an integral LCD. The CDT-2E44-LCD is the corresponding version with an integral LCD display.
Is the CDT-2E44 wall or duct mounted?
It is a wall-mount model with a European housing.
Can the transmitter be field calibrated?
Yes. The CDT series provides field calibration capability and digital barometric pressure adjustment.
