Air Velocity Transmitter

Air Velocity Transmitter

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:
• Display
• Field adjustable relay

Optional relay output : Will work as Air flow Switch

• Multiple sensing points for greater accuracy
• Easy installation
• Chamfered sensing points for consistent readings
• 2 % accuracy
• 2.5 X signal amplification
• Accepts 1/4″ OD tubing
