esco2d2a – co2 2000ppm duct transmitter current output
Carlo Gavazzi ESCO2D2A is a duct-mounted NDIR carbon dioxide transmitter with a 0–2000 ppm measuring range, 4–20 mA analogue output and 12–36 V DC or 24 V AC supply for HVAC and building automation systems.
Why Choose the Carlo Gavazzi ESCO2D2A CO2 Duct Transmitter?
The Carlo Gavazzi ESCO2D2A is a professional duct-mounted carbon dioxide (CO2) transmitter designed for accurate monitoring of indoor air quality in HVAC, ventilation and building automation systems. As part of the Carlo Gavazzi ESCO2 series, it uses non-dispersive infrared (NDIR) sensing technology to provide dependable CO2 measurement without the consumable elements associated with some alternative gas-sensing technologies.
The ESCO2D2A provides a 0–2000 ppm CO2 measuring range and converts the measured concentration into a standard 4–20 mA analogue current output. This industry-standard signal enables straightforward integration with compatible building management systems, HVAC controllers, PLCs and other monitoring equipment.
Designed specifically for air-duct mounting, the transmitter allows CO2 concentration to be monitored directly within ventilation systems. It can operate from a 12–36 V DC or 24 V AC power supply, while its plastic transmitter housing provides IP65 protection for dependable installation in building services and environmental monitoring applications.

Reliable CO2 Monitoring for HVAC and Building Automation
Monitoring carbon dioxide concentration provides an effective indication of occupancy-related indoor air quality and enables ventilation systems to respond to changing conditions. The ESCO2D2A measures CO2 directly within an air duct and converts the measurement into a standard 4–20 mA signal that can be monitored by compatible control equipment.
When incorporated into a demand-controlled ventilation system, CO2 measurement can help controllers adjust ventilation according to actual requirements rather than operating continuously at maximum airflow. This can help maintain comfortable indoor conditions while supporting more efficient operation of fans, air-handling units and other HVAC equipment.
Typical Applications
- HVAC air-duct CO2 monitoring.
- Demand-controlled ventilation systems.
- Building management systems.
- Air-handling units and ventilation equipment.
- Indoor air quality monitoring.
- Commercial and public buildings.
- Building automation and environmental control systems.
