Dwyer AVUL-3DA1 Air Velocity Transmitters

Dwyer AVUL-3DA1 Air Velocity Transmitters

The Dwyer Series AVUL Air Velocity Transmitters measure air velocity or volumetric flow in imperial or metric units. The series is designed for use with clean air and non-combustible, compatible gases. Models provide simultaneous current and voltage outputs to serve as universal inputs to monitoring equipment.

Operating Conditions & Performance
The Series AVUL operates within a process temperature range of 32 to 122°F (0 to 50°C) with an ambient humidity rating of 5 to 95% RH, non-condensing. Accuracy is specified as ±(0.2 m/s + 5% of reading) or ±(0.2 m/s + 3% of reading) @ standard conditions, depending on the model selected.

Measurement ranges are field selectable: 1000, 2000, 3000, 4000 FPM (5, 10, 15, 20 m/s).
The typical response time is 10 s (90%).
Power requirements are 24 VDC ±20% or 24 VAC ±20%.
Load resistance limits: Current output 0 to 1100 Ω max; Voltage output minimum load resistance 1 kΩ.
