cgesco2d5sl – co2 switch output 5000ppm probe 200mm – duct mounting
Carlo Gavazzi CGESCO2D5SL duct-mounted CO2 sensor and switch with a 0–5000 ppm measuring range, single relay switching output, 15–35 V DC or 24 V AC supply and 200 mm probe for HVAC and ventilation control.
Why Choose the Carlo Gavazzi CGESCO2D5SL CO2 Duct Switch?
The Carlo Gavazzi CGESCO2D5SL is a reliable duct-mounted CO2 sensor and switch designed for carbon dioxide monitoring and ventilation control in HVAC and building automation systems. As part of the Carlo Gavazzi CGES environmental sensor series, it measures CO2 concentrations across a 0–5000 ppm range and provides a relay switching output for direct integration with ventilation and control equipment.
The sensor is designed to monitor carbon dioxide concentration within ventilation ductwork, allowing building control systems to respond when CO2 reaches the configured switching level. This makes it particularly useful for demand-controlled ventilation, where fresh-air supply can be controlled according to actual indoor air-quality requirements rather than operating continuously at maximum ventilation rates.
With a 0–5000 ppm CO2 measurement range, single relay switching output, 15–35 V DC or 24 V AC supply and 200 mm duct probe, the CGESCO2D5SL provides a practical solution for commercial and industrial ventilation control. Its dedicated duct-mounted format allows the sensing probe to be positioned directly within the airflow for representative CO2 monitoring.

Reliable CO2 Switching for Ventilation Control
Carbon dioxide concentration is commonly used as an indicator of occupancy and indoor air quality in buildings. Monitoring CO2 within ventilation ductwork allows an HVAC system to determine when additional fresh air is required, helping maintain suitable indoor conditions while supporting more efficient operation of ventilation equipment.
Unlike analogue-output versions of the CGES CO2 duct sensor, the CGESCO2D5SL provides a relay switching output. This enables the sensor to provide a switching signal when the applicable CO2 threshold is reached, making it suitable for controlling compatible fans, dampers, controllers or building management system inputs without requiring a continuously variable CO2 output signal.
Typical Applications
- HVAC and ventilation control systems.
- Demand-controlled ventilation.
- Building management systems (BMS).
- Commercial building indoor air-quality monitoring.
- Air handling units and ventilation ductwork.
- Offices and commercial premises.
- Schools, colleges and educational buildings.
- Public buildings and occupied spaces.
- Industrial ventilation systems.
- Energy-efficient building automation systems.
