esavtd20v – air velocity temp duct tx voltage output
Carlo Gavazzi ESAVTD20V is a duct-mounted air velocity and temperature transmitter with a 0–20 m/s airflow range, 0–50 °C temperature measurement and 0–10 V analogue outputs for HVAC and building automation systems.
Why Choose the Carlo Gavazzi ESAVTD20V Air Velocity and Temperature Transmitter?
The Carlo Gavazzi ESAVTD20V is a professional duct-mounted air velocity and temperature transmitter designed for HVAC monitoring, building automation and environmental control applications. Part of the Carlo Gavazzi ESAVT environmental sensor series, it combines thermal air velocity measurement and temperature monitoring within a single compact transmitter.
The ESAVTD20V measures air velocity across a 0–20 m/s range while also monitoring temperatures from 0–50 °C. It provides 0–10 V analogue outputs, enabling both measured parameters to be integrated with compatible building management systems, HVAC controllers, PLCs and other automation equipment.
Designed specifically for air-duct mounting, the ESAVTD20V operates from an 8–35 V DC or 13–30 V AC supply. This model is supplied without an integral display or Modbus communication, making it a practical choice where straightforward analogue transmission of air velocity and temperature measurements is required.
