estc2wam – temperature humidity & co2 2000ppm wall
Carlo Gavazzi ESTC2WAM is a wall-mounted temperature and NDIR CO2 transmitter with a 0–2000 ppm CO2 range, 0–50 °C temperature range, 4–20 mA analogue output and RS485 Modbus communication for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESTC2WAM Temperature and CO2 Wall Transmitter?
The Carlo Gavazzi ESTC2WAM is a wall-mounted temperature and carbon dioxide (CO2) transmitter designed for indoor air quality monitoring, HVAC control and building automation systems. It combines temperature measurement with NDIR carbon dioxide sensing in a single device, helping building controllers monitor environmental conditions and manage ventilation more effectively.
The ESTC2WAM measures carbon dioxide concentrations across a 0–2000 ppm range and temperature from 0–50 °C. It provides a standard 4–20 mA analogue current output together with RS485 Modbus communication, enabling integration with compatible building management systems, HVAC controllers and automation networks.
Designed for wall mounting, the ESTC2WAM operates from 8–35 V DC or 12–30 V AC. Its housing provides IP54 protection, while the sensing element is rated IP20, making the transmitter well suited to indoor environmental monitoring in commercial, institutional and other building automation applications.
