Part No. CDT-2E40-LCD
Product Overview
The Dwyer Series CDT Carbon Dioxide Transmitters accurately monitor CO₂ concentration in indoor environments to support ventilation control and energy-saving applications. The CDT-2E40-LCD is a wall-mount European housing model with a 0-2000 ppm CO₂ range, no temperature output and an integral LCD display.
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-2E40 is the same transmitter without the integral LCD display.

How to Specify & Commission It
- Confirm the 0-2000 ppm CO₂ range, dedicated CO₂ measurement 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.
- Set the barometric pressure and perform field calibration if required.
- Configure the menu and lock it with the internal DIP switch if required.
- Verify the CO₂ reading at the connected controller and confirm the LCD display operates correctly.
Frequently Asked Questions
What does the CDT-2E40-LCD measure?
It measures CO₂ from 0-2000 ppm only. This model does not provide a 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-2E40-LCD?
CO₂ accuracy is ±40 ppm + 3% of reading at 2000 ppm.
What sensor technology is used?
It uses a single-beam, dual-wavelength NDIR sensor with a 15-year life expectancy.
Does the CDT-2E40-LCD have an LCD display?
Yes. This model has an integral LCD display for local CO₂ monitoring.
Is the CDT-2E40-LCD 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.
Is a non-LCD version available?
Yes. The CDT-2E40 is the same dedicated CO₂ transmitter without the integral LCD display.
