AVT Air flow and velocity transmitters

AVT

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 ollar 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
