AVT 551 – Air Velocity Transmitter

The AVT 551 is tailored for applications requiring lower air velocity measurement ranges. It offers selectable ranges of 0-1 m/s, 0-2 m/s, 0-3 m/s, or 0-5 m/s, configurable through DIP switches. It provides two outputs for air velocity: 4-20 mA and 0-10 Vdc, catering to diverse system needs.

Key specifications:

Air Velocity Accuracy: ±5% for 0-5 m/s
Temperature Accuracy: ±0.5°C at a minimum air velocity of 1 m/s
Power Supply: 24 Vac/dc
Response Time: Selectable 1 second or 5 seconds via DIP switches
Enclosure and Probe: IP65-rated enclosure with a durable plastic probe

Common Features Across AVT Series
- Sensor Placement: Located at the probe tip for accurate air velocity and temperature measurements.
- Enclosure Design: IP65-rated housing with easy access via one screw and two snap lids. Includes a plastic cable entry gland.
- Probe Material: Durable plastic construction for long-term use.
- Mounting Flange: Includes a duct mounting flange with a neoprene gasket for secure and adjustable installation.
- Optional Features (On Request):
  - Alternative outputs (2-10 Vdc, 0-5 Vdc, or 1-5 Vdc)
  - Second output (AO2) configurable for temperature output instead of air velocity
This detailed breakdown ensures all product features and differentiators are presented clearly for easy selection based on application requirements.
