Dwyer AVUL-3DB1 : Duct Mount Air Velocity Transmitter, 3% Accuracy, Field selectable 1000, 2000, 3000, 4000 FPM, BACnet MS/TP and 4-20 mA, 0-5 VC, 0-10 VDC Outputs, 5 Year Warranty
The Series AVUL Air Velocity Transmitters deliver precise and efficient measurement of air velocity or volumetric flow, available in both imperial and metric units. Each model features simultaneous current and voltage outputs, ensuring seamless integration with a variety of monitoring systems. Configuration of output ranges, units, and 0 to 5/10 VDC or 4-20 mA output is made simple using onboard DIP switches. With BACnet MS/TP communication protocols, these transmitters support daisy-chaining and provide access to comprehensive data, including velocity, flow, and air temperature.
Features
- Minimal preventative maintenance as the sensing element is covered with an engineered protective coating.
- Easy field setup via the onboard DIP switches for range and unit configuration.
Product Applications
- Variable Air Volume (VAV) systems
- Building duct monitoring
