cgeshtpda1s – hum/temp passive 50mm output 4-20ma pt100 – duct mounting
Carlo Gavazzi CGESHTPDA1S is a duct-mounted humidity and temperature sensor with a 50 mm probe, 10–95% RH measuring range, loop-powered 4–20 mA humidity output and passive Pt100 temperature element for HVAC applications.
Why Choose the Carlo Gavazzi CGESHTPDA1S Humidity and Temperature Sensor?
The Carlo Gavazzi CGESHTPDA1S is a duct-mounted humidity and temperature sensor designed for environmental monitoring in HVAC and building automation systems. It combines active relative humidity measurement with passive Pt100 temperature sensing, allowing two important air-conditioning parameters to be monitored from a single duct-mounted device.
The CGESHTPDA1S features a compact 50 mm probe for installation into ventilation ducts and air-handling systems. Its relative humidity channel covers 10–95% RH and provides an industry-standard 4–20 mA DC output, while temperature is measured using an integrated passive Pt100 resistance element.
The humidity transmitter is loop powered, making it suitable for integration with compatible HVAC controllers, PLC analogue inputs and building management systems. The combination of a 4–20 mA humidity signal and passive Pt100 temperature output provides a practical solution for monitoring duct air conditions in commercial and industrial ventilation installations.

Reliable Duct Humidity and Temperature Monitoring
Monitoring relative humidity and temperature within ventilation ductwork provides valuable information for HVAC control, comfort management and environmental regulation. The Carlo Gavazzi CGESHTPDA1S combines both measurements in one compact probe, reducing the need to install separate humidity and temperature sensing devices.
The 4–20 mA humidity signal provides a robust analogue interface for compatible building management and control systems, while the passive Pt100 element allows temperature to be measured using a conventional resistance input. Its 50 mm probe makes the CGESHTPDA1S particularly suitable where a compact insertion depth is preferred.
