Air Velocity Transmitter Mode AVT
Application and Features
-
It is designed for air velocity monitoring and controlling in the ventilation system and reducing energy consumption in BMS and various HVAC applications
-
Used for continuous measurement of single-point air velocity. AVT2 is used for general duct installation, AVT4 is used for remote installation
-
Based on thermal anemometer principle, use innovative and sensitive hot-film sensor, which is insensitive to dust and dirt, easy to install and maintain
-
No moving parts, provide accurate, reliable, sensitive and long-term measurement, with good temp. compensation
-
Digital technology applied to ensure output accuracy
-
Over voltage and reverse polarity protection with high reliability and anti-interference capacity
-
Multiple outputs and optional LCD display
-
Innovative probe structure design, various probe lengths available, with scales on
-
