estdd50vm – temp dew point duct tx voltage output with com
Carlo Gavazzi ESTDD50VM is a duct-mounted temperature and dew point transmitter with -40 to +100 °C temperature measurement, -40 to +60 °C dew point measurement, 0–10 V analogue output and RS485 Modbus RTU communication.
Why Choose the Carlo Gavazzi ESTDD50VM Temperature and Dew Point Transmitter?
The Carlo Gavazzi ESTDD50VM is a versatile duct-mounted temperature and dew point transmitter designed for environmental monitoring in HVAC, ventilation, clean-room and building automation systems. As part of the Carlo Gavazzi EST environmental sensor series, it combines temperature and dew point measurement in a single transmitter for efficient monitoring of air conditions.
The ESTDD50VM provides 0–10 V analogue outputs together with integrated RS485 Modbus RTU communication, allowing measurements to be connected to both conventional analogue controllers and modern digital building management systems. The transmitter measures temperature across a wide -40 to +100 °C range and dew point from -40 to +60 °C.
Designed specifically for air duct mounting, the ESTDD50VM is suitable for monitoring temperature and condensation-related conditions directly within ventilation and air-handling systems. It operates from an 8–35 V DC or 12–30 V AC supply, with an IP65 housing and an operating ambient temperature range of -20 to +60 °C for dependable commercial and industrial installation.

Reliable Temperature and Dew Point Monitoring
Temperature and dew point monitoring provides valuable information about environmental conditions within HVAC and ventilation systems. Dew point indicates the temperature at which moisture in the air can begin to condense, making continuous measurement useful for managing condensation risk, environmental conditions and process requirements.
The ESTDD50VM combines 0–10 V analogue signalling with RS485 Modbus RTU communication, enabling integration with PLCs, HVAC controllers, building management systems and other automation equipment. Its wide temperature range and duct-mounted sensing arrangement make it particularly suitable for air-handling systems, environmental control, clean rooms and industrial facilities.
Typical Applications
- HVAC temperature and dew point monitoring.
- Ventilation and air-handling systems.
- Building management systems.
- Condensation monitoring and control.
- Clean rooms and controlled environments.
- Environmental monitoring systems.
- Commercial and industrial buildings.
- Factories and manufacturing facilities.
- PLC-based environmental control systems.
