Air Velocity Transmitter

      Categories Flow, Air Flow Switch

      The AVT is an electronic air velocity and temperature transmitter for air and non-combustible gases with optional relay output.

      AVT air velocity transmitters are engineered for building automaton in the HVAC/R industry. They are electronic air velocity and temperature transmitters for air. They measure air velocity and temperature in ventilation ducts, with field selectable options for measurement range and output settings in a single device.

      AVT has a duct mount probe and an adjustable duct flange suitable for round or rectangular ducts.
