Why Choose the Carlo Gavazzi ESAVTR20AD Air Velocity and Temperature Transmitter?

The Carlo Gavazzi ESAVTR20AD is a professional air velocity and temperature transmitter designed for accurate monitoring of airflow and temperature in HVAC, building automation and environmental control systems. Part of the Carlo Gavazzi ESAVT environmental sensor series, this version uses a remote sensing probe, allowing measurements to be taken at a different location from the transmitter enclosure.

The ESAVTR20AD measures air velocity across a range of 0–20 m/s while simultaneously monitoring air temperature. It provides industry-standard 4–20 mA analogue outputs, making measured values straightforward to integrate with building management systems, PLCs, controllers and other monitoring equipment.

With an integrated LCD display, remote probe arrangement, 8–35 V DC / 12–30 V AC supply and protected plastic enclosure, the ESAVTR20AD provides a practical solution for ventilation monitoring, air handling equipment and HVAC control applications where reliable airflow and temperature information is required.

Reliable Airflow and Temperature Monitoring for HVAC Systems

Air velocity and temperature transmitters such as the Carlo Gavazzi ESAVTR20AD allow building automation and HVAC control systems to continuously monitor ventilation performance. Measuring airflow velocity helps controllers verify that the required volume of air is moving through ventilation and air handling systems, while temperature measurement provides additional information for environmental control.

The remote sensor arrangement enables the sensing probe to be positioned at the required measurement point while the transmitter and display remain conveniently accessible. Combined with standard 4–20 mA outputs, this makes the ESAVTR20AD suitable for integration into BMS, HVAC controllers, PLC-based monitoring systems and other environmental control equipment.

Typical Applications

• HVAC airflow monitoring systems.
• Building management systems (BMS).
• Air handling units and ventilation equipment.
• Supply and extract air monitoring.
• Commercial building environmental control.
• Industrial ventilation systems.
• Cleanroom and controlled-environment monitoring.
• Energy management and building automation systems.
