cgeshtdal – hum/temp 200mm output 4-20ma – duct mounting
Carlo Gavazzi CGESHTDAL is a duct-mounted humidity and temperature transmitter with a 200 mm probe, 10–95% RH and 0–50 °C measuring ranges, and 4–20 mA DC current-loop outputs for HVAC and building automation systems.
Why Choose the Carlo Gavazzi CGESHTDAL Humidity and Temperature Sensor?
The Carlo Gavazzi CGESHTDAL is a duct-mounted humidity and temperature transmitter designed for continuous environmental measurement in HVAC, ventilation and building automation systems. As part of the Carlo Gavazzi CGES environmental sensor range, it combines relative humidity and temperature measurement in a single industrial sensor with standard 4–20 mA current-loop outputs.
The CGESHTDAL measures relative humidity across a 10–95% RH range and temperature across a 0–50 °C range. Its 200 mm duct probe allows the sensing element to be positioned directly within an air duct, providing representative measurements of the air passing through ventilation and air-handling systems.
Both humidity and temperature are transmitted using industry-standard 4–20 mA DC analogue outputs, making the CGESHTDAL straightforward to integrate with compatible HVAC controllers, PLCs and building management systems. Its loop-powered design and dedicated duct-mounting format provide a practical solution for monitoring environmental conditions throughout commercial and industrial ventilation systems.

Reliable Humidity and Temperature Monitoring for HVAC Systems
Humidity and temperature are important parameters for controlling indoor climate, ventilation and air-conditioning systems. By measuring both conditions directly within an air duct, the Carlo Gavazzi CGESHTDAL allows compatible control systems to monitor supply, return or extract air and respond to changing environmental conditions.
The transmitter converts its humidity and temperature measurements into standard 4–20 mA current-loop signals, providing a robust interface for connection to HVAC controllers, PLC analogue inputs and building management systems. Its 200 mm probe is designed for insertion into ductwork, helping provide representative measurement of the air stream rather than the surrounding room environment.
Typical Applications
- HVAC air-handling units.
- Supply and return air duct monitoring.
- Commercial ventilation systems.
- Building management systems.
- Heating and cooling control systems.
- Industrial ventilation and process air monitoring.
- Environmental control and indoor climate systems.
