Application

CO2 transmitters can be used in a broad range of applications including air quality monitoring in buildings.

CO2 concentration levels in buildings are monitored to provide an indication of occupancy and to drive a ventilation control strategy.

An effective DCV (Demand Controlled Ventilation) strategy will conserve energy and maintain indoor air quality.

Technology

The technology is based on the absorption of light in a goldplated reflective light pipe or waveguide diffusion gas chamber.

A gas permeable PTFE filter prevents particulate and water contamination of the sensor. Light is absorbed in proportion to the CO2 concentration and the remaining light is measured and converted into an analog signal.

The CDD 041 is a CO2 transmitter designed to be installed in HVAC return air ducts. The CDD 041 offers simplicity in design and installation.
