esthw50a – temp rh wall tx current output

Why Choose the Carlo Gavazzi ESTHW50A Temperature and Humidity Wall Transmitter?

The Carlo Gavazzi ESTHW50A is a compact wall-mounted temperature and relative humidity transmitter designed for HVAC, building automation and indoor environmental monitoring applications. It combines temperature and humidity measurement in a single enclosure, providing two analogue signals for straightforward integration with compatible control and monitoring equipment.

The ESTHW50A measures temperature across a 0–50 °C range and relative humidity from 0–95% RH. The transmitter provides two 4–20 mA analogue current outputs, enabling temperature and humidity measurements to be transmitted to compatible HVAC controllers, PLCs and building management systems.

Designed for simple wall mounting, the ESTHW50A features a compact 85 × 85 × 30.2 mm housing and operates from an 11–35 V DC power supply. Its straightforward analogue interface makes it particularly suitable for commercial buildings, hotels, hospitals and environmental ventilation control systems where reliable room temperature and humidity monitoring is required.

Reliable Temperature and Humidity Monitoring for Building Automation

Temperature and relative humidity are important parameters for maintaining comfortable and controlled indoor environments. The ESTHW50A monitors both variables from a single wall-mounted device and converts each measurement into a standard 4–20 mA current signal for use by compatible HVAC and building automation equipment.

Its dual analogue outputs make the ESTHW50A straightforward to integrate with controllers equipped with standard current inputs. The compact wall-mounted format is particularly useful for room monitoring, air-conditioning control and environmental ventilation applications in commercial and institutional buildings.
