Why Choose the Carlo Gavazzi ESAVTR20AM Air Velocity and Temperature Transmitter?

The Carlo Gavazzi ESAVTR20AM is a reliable 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 ESAVT20 environmental sensor series, it combines thermal air velocity measurement with temperature monitoring in a single industrial sensing solution.

The ESAVTR20AM features remote sensor mounting, making it particularly suitable for installations where the sensing probe needs to be positioned separately from the transmitter housing. It provides a 4–20 mA analogue current output and RS485 Modbus communication, enabling straightforward integration with building management systems, PLCs and industrial monitoring equipment.

With an air velocity measuring range of 0.2–20 m/s and temperature measurement from 0–50 °C, the ESAVTR20AM provides versatile environmental monitoring across ventilation and air-handling applications. Its transmitter operates from 8–35 V DC or 12–30 V AC and uses a robust IP54 plastic housing for dependable operation in commercial and industrial installations.

Reliable Air Velocity and Temperature Monitoring

Air velocity transmitters provide continuous measurement of airflow within ventilation, environmental control and industrial air-handling systems. By converting measured air velocity into a standard analogue signal, the ESAVTR20AM allows airflow conditions to be monitored by PLCs, controllers and building management systems.

The ESAVTR20AM also monitors air temperature, providing two important environmental measurements from one sensing system. Its combination of 4–20 mA output and RS485 Modbus communication supports both conventional analogue control architectures and modern digital monitoring networks, while the remote sensing arrangement provides flexibility when positioning the measurement point.

Typical Applications

• HVAC airflow and temperature monitoring.
• Building management systems.
• Ventilation and air-handling equipment.
• Environmental control systems.
• Clean rooms and controlled environments.
• Laminar airflow monitoring.
• Industrial process ventilation.
• PLC and automation-based environmental monitoring systems.
