Carlo Gavazzi CGESCO2TW5AT04 is a wall-mounted CO₂ and temperature transmitter with 5000 ppm measuring range, 4–20 mA output, NDIR sensing technology and HVAC monitoring capability.
The Carlo Gavazzi CGESCO2TW5AT04 is a wall-mounted CO₂ and temperature transmitter designed for accurate indoor air quality monitoring and HVAC control applications. Using advanced Non-Dispersive Infrared (NDIR) technology for carbon dioxide measurement, this environmental sensor provides reliable CO₂ concentration and temperature monitoring with a 4–20 mA analogue output.
The CGESCO2TW5AT04 measures CO₂ concentrations up to 5000 ppm and provides a proportional 4–20 mA output for integration with building management systems, HVAC controllers and industrial monitoring equipment. Its wall-mounting design, compact housing and long-term stable NDIR sensing element make it suitable for continuous environmental monitoring.
Operating from a 24 V AC or 15–35 V DC supply, the transmitter features a compact polycarbonate housing, IP54 protection and a fast-response CO₂ measurement system. The device is designed for applications where accurate ventilation control and indoor air quality management are required.
CO₂ transmitters are widely used to monitor indoor air quality by measuring carbon dioxide concentration and providing feedback to ventilation systems. The CGESCO2TW5AT04 uses NDIR sensing technology to provide stable and accurate CO₂ measurement for automatic ventilation control and environmental monitoring.
By providing a standard 4–20 mA analogue signal, the transmitter can be easily integrated into building management systems, HVAC controllers and industrial monitoring platforms. Its wall-mounted format makes it suitable for offices, public buildings, laboratories, greenhouses and other environments where air quality management is important.
