esavtr20vdm – air velocity temp remote tx voltage output with
Carlo Gavazzi ESAVTR20VDM is a remote air velocity and temperature transmitter with a 0–20 m/s airflow range, 0–10 V analogue output, integrated display and Modbus RS485 communication for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESAVTR20VDM Air Velocity and Temperature Transmitter?
The Carlo Gavazzi ESAVTR20VDM is a versatile remote air velocity and temperature transmitter designed for HVAC, building automation and environmental monitoring applications. As part of the Carlo Gavazzi ESAVT series, it combines air velocity and temperature measurement with analogue output, local display and digital communication in a single monitoring solution.
The ESAVTR20VDM uses a remote sensing probe and measures air velocity across a 0–20 m/s range while also measuring temperatures from 0–50 °C. The remote configuration allows the probe to be positioned at the required airflow measurement point while the transmitter enclosure remains accessible for viewing, wiring and system integration.
This model provides a 0–10 V analogue output together with Modbus RS485 communication and an integrated display, enabling connection to HVAC controllers, PLCs and building management systems. Its 8–35 V DC / 12–30 V AC supply and IP54 plastic housing make it a flexible solution for commercial and industrial environmental control installations.

Reliable Airflow and Temperature Monitoring
Air velocity and temperature transmitters provide continuous environmental measurements for ventilation, HVAC and building automation systems. By converting measured conditions into standard analogue signals and digital data, the transmitter enables control systems to monitor airflow performance, regulate ventilation and maintain appropriate environmental conditions.
The ESAVTR20VDM adds Modbus RS485 communication to its 0–10 V analogue interface, allowing measurements to be integrated into both conventional analogue control loops and networked building management systems. Its remote probe configuration is particularly useful where the sensing location must be separated from the transmitter and display.
Typical Applications
- HVAC air velocity and temperature monitoring.
- Building management systems.
- Ventilation and air-conditioning installations.
- Air duct and airflow monitoring.
- Industrial environmental control systems.
- Clean-room and controlled-environment ventilation systems.
- Energy management and intelligent building automation.
- Modbus-connected environmental monitoring networks.
