cgeshtpwa1 – hum/temp passive output 4-20ma pt100 – wall mounting
Carlo Gavazzi CGESHTPWA1 is a wall-mounted humidity and temperature environmental sensor with a 0–95% RH range, 4–20 mA humidity output and passive Pt100 DIN A temperature element for HVAC and building automation applications.
Why Choose the Carlo Gavazzi CGESHTPWA1 Humidity and Temperature Sensor?
The Carlo Gavazzi CGESHTPWA1 is a wall-mounted humidity and temperature environmental sensor designed for HVAC, ventilation and building automation applications. As part of the Carlo Gavazzi CGES environmental sensor range, it combines a 4–20 mA humidity output with a passive Pt100 DIN A temperature sensing element for reliable monitoring of indoor environmental conditions.
The CGESHTPWA1 uses a high-quality capacitive humidity sensing element and microprocessor-controlled electronics to provide dependable relative humidity measurement. Its standard 4–20 mA current-loop output is well suited to building management systems, HVAC controllers and compatible industrial control equipment where robust analogue signal transmission is required.
Temperature measurement is provided independently by a passive Pt100 DIN A resistance sensor, allowing a compatible controller to monitor temperature alongside the active humidity signal. Designed for wall mounting and supplied without a display, the CGESHTPWA1 provides a compact solution for monitoring occupied rooms and other controlled indoor environments.

Reliable Humidity and Temperature Monitoring for Building Automation
Accurate monitoring of relative humidity and temperature is important for maintaining comfortable indoor conditions and supporting efficient HVAC control. The Carlo Gavazzi CGESHTPWA1 combines both measurements in one wall-mounted device, allowing environmental conditions to be monitored without installing separate humidity and temperature sensors.
The 4–20 mA humidity output provides a robust current signal for compatible controllers and building management systems, while the passive Pt100 element provides a resistance-based temperature signal. This combination makes the CGESHTPWA1 particularly suitable for building automation systems that require an analogue humidity signal together with passive temperature sensing.
Typical Applications
- HVAC and climate-control systems.
- Building management systems.
- Indoor relative humidity monitoring.
- Room temperature monitoring.
- Commercial buildings and offices.
