esthwa – temperature & humidity wall transmitter current
Carlo Gavazzi ESTHWA is a wall-mounted temperature and relative humidity transmitter with 0–50 °C temperature measurement, 0–100% RH measurement and 4–20 mA analogue current output for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESTHWA Temperature and Humidity Transmitter?
The Carlo Gavazzi ESTHWA is a compact wall-mounted temperature and relative humidity transmitter designed for continuous environmental monitoring in HVAC, building automation and indoor climate control applications. Combining temperature and humidity measurement in a single device simplifies installation while providing the key environmental signals required by compatible control systems.
The ESTHWA measures temperature across a 0–50 °C range and relative humidity across 0–100% RH. Its standard 4–20 mA analogue current output provides a robust industrial signal for connection to compatible PLCs, HVAC controllers and building management systems, particularly where reliable transmission over longer cable runs is required.
Designed specifically for wall mounting, the ESTHWA operates from a flexible 8–35 V DC or 12–30 V AC supply. The transmitter features an IP54 housing, IP20 sensing element and M12 electrical connection, making it a practical solution for commercial buildings, offices, environmental control systems and other indoor temperature and humidity monitoring applications.

Temperature and Humidity Monitoring for HVAC Systems
Temperature and relative humidity are fundamental parameters for controlling indoor environmental conditions. Continuous measurement enables HVAC and building automation systems to respond to changes in room conditions, helping regulate heating, cooling, ventilation and humidity-control equipment according to the requirements of the occupied space or process.
The ESTHWA converts measured environmental conditions into a standard 4–20 mA current signal, providing a widely used interface for industrial and building automation equipment. Its wall-mounted construction makes it particularly suitable for monitoring room conditions in offices, commercial premises, storage areas and other controlled indoor environments.
