The AVT is an electronic air velocity and temperature transmitter for air and non-combustible gases with optional relay output.
AVT series air velocity transmitters are engineered for building
automation in the HVAC/R industry. The AVT measures air velocity and
temperature, with field selectable range and output options in a
single device. Designed with a duct mount probe and adjustable
collar suitable for round or rectangular ducts.
AVT series devices include:
• 3 field selectable measurement ranges for air velocity, selectable via jumper.
• Separate readings and outputs for air velocity and temperature.
• Proportional output options include: voltage (0–10 V) and current (4–20 mA).
AVT series device options offer:
• Backlit display
• Field adjustable relay
