Dwyer AVLV-1DB1 : Duct Mount Low Air Velocity Transmitter, 1% Accuracy, Field selectable 100, 200, 300, 400 FPM, BACnet MS/TP and 4-20 mA, 0-5 VC, 0-10 VDC Outputs, 5 Year Warranty
The Series AVLV Air Velocity Transmitter offers precise measurement of air velocity or volumetric flow in both imperial and metric units. Featuring simultaneous current and voltage outputs, it ensures compatibility with a wide range of monitoring equipment. The device's output range, units, and 0-5/10 VDC or 4-20 mA signals are easily configurable through local DIP switches. Users can monitor and configure process values conveniently with the optional integral display or a portable remote tool.
The transmitter includes low-velocity ranges to meet diverse application needs. Optional BACnet MS/TP communication protocols enable seamless daisy-chaining while providing comprehensive data access, including air velocity, volumetric flow, and air temperature. Designed for high accuracy and lower ranges, these units are ideal for quality-sensitive environments, such as the pharmaceutical industry.
