CARBON MONOXIDE TRANSMITTERS

Carbon monoxide transmitter for detecting CO concentration in air

CMT, carbon monoxide transmitter, is an easy-to-use, reliable transmitter for detecting CO gas. It is commonly used to control ventilation in areas where high concentrations of CO may cause serious health problems.

CMT devices are commonly used in places where air includes CO gas emissions, such as:
• Commercial parking garages
• Apartment garages
• Tunnels and terminals
• Car and bus maintenance garages
• Warehouses and factories
• Auto service centers

CARBON DIOXIDE TRANSMITTERS
CDT-MOD-2000 Series

Multifunctional CO2 transmitters for building automation systems that use Modbus serial communication protocol

CDT series air quality transmitters are engineered for building automation systems in the HVAC/R industry. The CDT 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. CDT series devices are available with large touchscreen display making configuration of the device quick and easy. Configuration is also possible via Modbus network.

The CDT-MOD-2000 series transmitters calibrate themselves automatically using ABC logicTM. The ABC logicTM requires that the space in which the transmitter is used needs to to be unoccupied for four hours per day so that the indoor CO2concentration drops to the outside level. CDT-MOD-2000-DC is a dual channel model with a measuring channel and a reference channel that makes a continuous comparison and the necessary adjustment accordingly. CDT-MOD-2000-DC is also suitable for buildings that are continuously occupied.

CDT series devices include:

• Separate field configurable Modbus output for each measurement parameter (CO2, rH, T)
• One analog output for selected measurement: voltage (0/2–10 V) or current (4–20 mA)
•  2″ x 3″ touchscreen display
• Optional relay output

APPLICATIONS CDT-MOD-2000 series devices are commonly used to monitor:

• CO2 and humidity levels in offices, public spaces, meeting rooms and classrooms
• CO2 levels of return air in ventilation systems
• incoming air and return air humidity levels in ventilation system • humidity in various industrial applications
• temperatures in HVAC/R environment
• CDT-MOD-2000-DC series devices can also be used in applications where there is a constant source of carbon dioxide present (for example hospitals and greenhouses)
