estc5wa – temperature & co2 5000ppm wall transmitter current
Carlo Gavazzi ESTC5WA is a wall-mounted temperature and NDIR CO2 transmitter with a 0–5000 ppm CO2 range and 4–20 mA analogue current outputs for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESTC5WA Temperature and CO2 Transmitter?
The Carlo Gavazzi ESTC5WA is a compact wall-mounted temperature and carbon dioxide (CO2) transmitter designed for indoor air-quality monitoring, HVAC control and building automation applications. As part of the Carlo Gavazzi EST environmental sensor range, it combines temperature measurement with non-dispersive infrared CO2 sensing in a single device for continuous monitoring of occupied indoor environments.
The ESTC5WA measures temperature from 0–50 °C and CO2 concentration from 0–5,000 ppm. Its extended CO2 measuring range makes it suitable for building and ventilation applications where carbon dioxide levels need to be monitored over a wider concentration range than conventional 2,000 ppm room sensors.
This model provides 4–20 mA analogue current outputs for straightforward integration with HVAC controllers, PLCs and building management systems. With a flexible 8–35 V DC / 12–30 V AC supply, M12 plug connection and compact wall-mounted enclosure, the ESTC5WA provides a practical solution for environmental monitoring and demand-controlled ventilation systems.

Reliable Temperature and CO2 Monitoring for Building Automation
Temperature and carbon dioxide transmitters provide continuous environmental measurements that can be used by HVAC controllers and building management systems to monitor indoor conditions. CO2 concentration can be used as an input for demand-controlled ventilation, while temperature measurement provides additional information for maintaining controlled and comfortable indoor environments.
The ESTC5WA converts its temperature and CO2 measurements into standard 4–20 mA analogue signals, providing a robust interface for compatible industrial and building automation controllers. Its wall-mounted construction makes it particularly suitable for monitoring occupied spaces and other indoor locations where local temperature and CO2 measurement is required.
Typical Applications
- HVAC temperature and CO2 monitoring.
- Demand-controlled ventilation systems.
- Building management systems.
- Indoor air-quality monitoring.
- Offices and commercial buildings.
- Schools and educational facilities.
- Public and institutional buildings.
- Industrial environmental monitoring.
