Product Description

AVT air velocity transmitters are engineered for building automation 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.
