Dwyer AVLV-2DA1-LCD : Duct Mount Low Air Velocity Transmitter, 2% Accuracy, Field selectable 100, 200, 300, 400 FPM, 4-20 mA, 0-5 VC, 0-10 VDC Outputs, LCD Display, 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. Designed for high accuracy and lower ranges, these units are ideal for quality-sensitive environments, such as the pharmaceutical industry.
