Why Choose the Carlo Gavazzi CGESHTDVS Humidity and Temperature Duct Transmitter?

The Carlo Gavazzi CGESHTDVS is a compact and reliable humidity and temperature duct transmitter designed for environmental monitoring in HVAC, ventilation and building automation systems. As part of the Carlo Gavazzi CGES environmental sensor series, it provides simultaneous measurement of relative humidity and temperature with standard 0–10 V DC analogue outputs for straightforward integration with building management and control systems.

Designed specifically for ventilation duct installation, the CGESHTDVS measures air conditions directly within the duct rather than relying on room-level measurements. This allows HVAC controllers and building management systems to monitor humidity and temperature within the airflow and use these measurements for ventilation, heating, cooling, humidification and dehumidification control.

The CGESHTDVS measures relative humidity across a 10–95% RH range and temperature across a 0–50 °C range. It provides separate 0–10 V DC outputs for humidity and temperature, operates from a 15–35 V DC or 24 V AC supply and incorporates a compact 50 mm duct probe for installations where a shorter insertion length is required.

Reliable Humidity and Temperature Monitoring for HVAC Systems

Humidity and temperature are fundamental measurements in heating, ventilation and air-conditioning systems. Monitoring both parameters directly within ventilation ductwork allows a building control system to evaluate the condition of the supplied or extracted air and make appropriate adjustments to heating, cooling, humidification and dehumidification equipment.

The CGESHTDVS converts its humidity and temperature measurements into separate 0–10 V DC analogue signals. These standard control signals can be connected to compatible analogue inputs on building management systems, HVAC controllers and PLCs, providing continuous measurement rather than simple switching information. Its compact 50 mm probe makes the transmitter particularly suitable for duct installations where available insertion depth is limited.
