cgesco2d2al – co2 output 4-20ma
Carlo Gavazzi CGESCO2D2AL is a duct-mounted CO2 environmental sensor with a 0–2000 ppm measuring range, 4–20 mA analogue output and 200 mm probe for HVAC and building automation systems.
Why Choose the Carlo Gavazzi CGESCO2D2AL CO₂ Duct Sensor?
The Carlo Gavazzi CGESCO2D2AL is a dedicated duct-mounted CO₂ environmental sensor designed for measuring carbon dioxide concentrations in HVAC, ventilation and building automation systems. As part of the Carlo Gavazzi CGES environmental sensor range, it combines a 0–2000 ppm CO₂ measuring range with an industry-standard 4–20 mA analogue output for straightforward integration with controllers and building management systems.
Designed specifically for air-duct monitoring, the CGESCO2D2AL uses a 200 mm probe to sample conditions within ventilation ductwork. The analogue current output allows the measured CO₂ concentration to be transmitted to compatible PLCs, HVAC controllers and building management systems for continuous monitoring and demand-controlled ventilation.
With its 15–35 V DC or 24 V AC supply, dedicated CO₂ measurement and robust duct-mounted configuration, the CGESCO2D2AL provides a practical solution for monitoring indoor air quality and controlling ventilation according to actual carbon dioxide levels.

Reliable CO₂ Monitoring for HVAC and Ventilation Systems
Carbon dioxide monitoring provides an effective way to assess ventilation demand in occupied buildings. By continuously measuring CO₂ concentration within an air duct, the Carlo Gavazzi CGESCO2D2AL can provide a proportional signal to a compatible controller, enabling ventilation equipment to respond to changing indoor conditions.
The 4–20 mA output is widely used in industrial and building automation because it provides a robust analogue signal suitable for transmission to HVAC controllers, PLCs and building management systems. Combined with its 200 mm duct probe, the CGESCO2D2AL is well suited to centralised air-quality monitoring and demand-controlled ventilation installations.
