Part Number: AVLV-1DA1
The Dwyer AVLV-1DA1 is a duct-mount air velocity transmitter built for reliable airflow measurement and straightforward BMS integration. It provides 1% accuracy across field-selectable ranges of 100, 200, 300, or 400 FPM (0.5, 1, 1.5, or 2 m/s), allowing the transmitter to be configured according to the requirements of the HVAC application.
The transmitter features universal current/voltage analog outputs, including 4–20 mA, 0–5 VDC, and 0–10 VDC, making it suitable for controllers and BMS systems that use analog inputs.
Its NEMA 4X (IP66) enclosure provides protection for installation in mechanical rooms and plenum spaces. The unit operates from 32 to 122°F (0–50°C) with 5–95% RH non-condensing humidity tolerance, covering typical duct and HVAC operating conditions.
Response time is approximately 4 seconds under typical conditions and 1 second at constant temperature, supporting standard VAV and AHU control applications. The transmitter operates on 24 VDC or 24 VAC, with a maximum current consumption of 60 mA.
This version does not include an onboard display. Air velocity readings are transmitted to and viewed through the connected BMS or controller. The compact 6.0 oz housing allows convenient installation with a standard duct probe assembly. The AVLV-1DA1 also carries BTL and CE approvals.
If your application requires a local display, the Dwyer AVLV-1DA1-LCD provides the same general transmitter configuration with an integrated LCD display.
