Part No.: AVLV-2DA1-LCD
The Dwyer AVLV-2DA1-LCD Air Velocity Transmitter is a duct-mount air velocity transmitter designed for integration with building management systems and HVAC controllers through universal current/voltage analog outputs. It provides 2% accuracy across field-selectable velocity ranges of 100, 200, 300, or 400 FPM (0.5, 1, 1.5, or 2 m/s).
The transmitter features a NEMA 4X (IP66) enclosure, providing protection for installations in mechanical rooms, plenum spaces, and typical HVAC environments. It operates across 32 to 122°F (0 to 50°C) with a 5–95% RH non-condensing humidity tolerance.
With a typical response time of approximately 4 seconds, or approximately 1 second at constant temperature, the AVLV-2DA1-LCD is suitable for standard VAV and AHU control applications. The transmitter operates on 24 VDC or 24 VAC power with a maximum current consumption of 60 mA.
A built-in 5-digit LCD provides local air velocity readings at the transmitter, making commissioning, troubleshooting, and field verification easier without requiring a laptop.
The universal analog output configuration supports 4–20 mA, 0–5 VDC, or 0–10 VDC, making the transmitter suitable for controllers that require standard current or voltage inputs rather than a fieldbus connection.
The compact 6.0 oz body is designed for installation with a standard duct probe assembly. BTL and CE approvals support its use in building automation and general electrical applications.
The Dwyer range also includes the AVLV-2DA1, which provides the same type of universal current/voltage output functionality without the onboard LCD. Contact GeneralTech Shop if you need help selecting the correct variant.
