CO2

CARBON DIOXIDE TRANSMITTERS
CDT2000 Series
Multifunctional, wall mount CO2 transmitters for building automation
systems
The CDT2000 series air quality transmitters are engineered for building automation systems in the HVAC/R industry. The CDT2000 series measures carbon dioxide (CO2), utilizing the industry standard
NDIR measurement principle, and temperature (T). Optional relative
humidity (rH) measurement is also available in the same device. The
CDT2000 series devices are available with large touchscreen display
making the configuration of the device quick and easy.
CDT2000 series devices include:
• tSeparate field configurable output for each measurement
parameter (CO2, rH, T).
• tProportional output options including: voltage (0–10 V, 2–10 V)
and current (4–20 mA).
CDT2000 series device options offer:
• t2” x 3” touchscreen display
• tField configurable relay for any of the three parameters
• tModbus configuration
The versatility of the CDT2000 series air quality transmitters ensures
that the right product for your application is available.

APPLICATIONS
CDT2000 series devices are commonly used to monitor:
• tCO2 and humidity levels in offices, public spaces, meeting rooms
and classrooms
• tCO2 levels of return air in ventilation systems
• tincoming air and return air humidity levels in ventilation system
