esavtr20vm – air velocity temp remote tx voltage output with
Carlo Gavazzi ESAVTR20VM is a remote-mount air velocity and temperature transmitter with a 0–20 m/s airflow range, 0–10 V analogue output and Modbus RS485 communication for HVAC and building automation applications.
Why Choose the Carlo Gavazzi ESAVTR20VM Air Velocity and Temperature Transmitter?
The Carlo Gavazzi ESAVTR20VM is a versatile air velocity and temperature transmitter designed for monitoring airflow and temperature in HVAC, building automation and environmental control applications. As part of the Carlo Gavazzi ESAVT series, this version uses a remote sensor arrangement and combines analogue voltage outputs with Modbus RS485 communication for flexible system integration.
The ESAVTR20VM measures air velocity across a range of 0–20 m/s while simultaneously monitoring air temperature. Its 0–10 V analogue outputs allow measured values to be transmitted to compatible controllers, PLCs and building management systems, while the integrated Modbus RS485 interface provides digital communication for modern automation networks.
Designed for remote sensor mounting, the ESAVTR20VM separates the sensing element from the transmitter enclosure, providing installation flexibility in ventilation and air-handling systems. The transmitter can be powered from 8–35 V DC or 12–30 V AC and is housed in a durable IP54 plastic enclosure suitable for environmental monitoring and HVAC control installations.

Reliable Airflow Monitoring for HVAC and Building Automation
Accurate air velocity monitoring is important for maintaining effective airflow through ventilation ducts, air-handling equipment and environmental control systems. The ESAVTR20VM converts measured air velocity and temperature into standard 0–10 V signals, enabling compatible controllers to monitor conditions and regulate fans, dampers and other HVAC equipment.
The addition of Modbus RS485 communication enables measured data to be integrated into digital building management and automation networks. Combined with its remote sensing arrangement, the ESAVTR20VM provides a flexible solution for installations where the measurement point needs to be positioned separately from the main transmitter enclosure.
Typical Applications
- HVAC air velocity and temperature monitoring.
- Building management systems.
- Ventilation and air-handling units.
- Commercial building environmental control.
- Airflow monitoring and control systems.
- Industrial ventilation equipment.
- Building and industrial automation systems.
