Part No.: AVLV-2DB1-LCD
The Dwyer AVLV-2DB1-LCD Air Velocity Transmitter is a duct-mount air velocity transmitter designed for direct integration into building management systems through BACnet MS/TP communication. 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 suitable for mechanical rooms and plenum spaces. It operates from 32 to 122°F (0 to 50°C) and supports 5–95% RH non-condensing humidity, covering typical HVAC duct and control environments.
With a typical response time of approximately 4 seconds, or approximately 1 second at constant temperature, the AVLV-2DB1-LCD is suitable for standard VAV and AHU control applications. The unit operates on 24 VDC or 24 VAC power with a maximum current consumption of 60 mA.
A built-in 5-digit LCD provides a local readout directly at the transmitter, making commissioning and field verification easier without requiring a laptop for every on-site check.
The AVLV-2DB1-LCD carries BTL and CE approvals, supporting its use in BACnet-based building automation and general electrical applications. Its compact 6.0 oz body is designed for installation with a standard duct probe assembly.
The Dwyer range also includes the AVLV-2DB1 Air Velocity Transmitter, which does not include the LCD display. Contact GeneralTech Shop if you need help confirming the correct variant for your application.
