Part Number-AVU-2-A
The Dwyer AVU-2-A provides a wider air velocity measurement range than the AVUB-1-V, covering 0–1575 FPM (0–8 m/s) with 5% accuracy. Its standard 4–20 mA current-loop output makes it suitable for connection to compatible analog inputs on building automation and control systems.
A 4–20 mA current-loop signal is particularly useful for installations involving longer cable runs between the transmitter and controller panel. Compared with voltage-based signals, current-loop signaling is less affected by voltage drop over longer wiring distances, making the AVU-2-A a practical option when the transmitter is installed farther from the control panel.
The compact transmitter is designed for straightforward duct or wall mounting and can be integrated into standard analog input points on compatible building automation systems. Its simple analog output helps reduce the need for additional communication protocols or fieldbus configuration.
For applications requiring a lower measurement range with a 0–10 VDC output, the Dwyer range also includes the AVUB-1-V Air Velocity Transmitter, which measures 0–785 FPM (0–4 m/s).
Key Benefits
- 0–1575 FPM (0–8 m/s) air velocity measurement range
- Standard 4–20 mA current-loop output
- 5% accuracy for general airflow monitoring
- Suitable for longer cable runs between the transmitter and controller
- Simple integration with compatible analog BAS inputs
- Compact design for duct or wall mounting
- Straightforward analog signaling without fieldbus configuration
Who This Product Is Best For
The Dwyer AVU-2-A is suitable for controls technicians, HVAC contractors, building automation professionals, and facility management teams who need a mid-range air velocity transmitter with a 4–20 mA current-loop output, particularly where the transmitter is located some distance from the controller panel.
How to Use
- Mount the AVU-2-A at the duct or wall location where airflow is being monitored.
- Connect the 4–20 mA current-loop output to the compatible analog input on the controller.
- Configure the controller scaling for the 0–1575 FPM (0–8 m/s) measurement range.
- Verify that the controller is receiving the expected analog signal.
- If precise calibration is required, compare the transmitter reading with a suitable reference anemometer.
Frequently Asked Questions
What is the velocity range of the AVU-2-A?
The AVU-2-A measures air velocity from 0 to 1575 FPM (0 to 8 m/s).
What output does the AVU-2-A provide?
It provides a standard 4–20 mA current-loop output for compatible analog controller inputs.
Why use a 4–20 mA output instead of 0–10 VDC?
A 4–20 mA current-loop signal is well suited to longer wiring runs because it is less affected by voltage drop than a voltage-based signal.
What accuracy does the AVU-2-A offer?
The AVU-2-A provides 5% accuracy.
What applications suit the AVU-2-A?
It is suitable for general airflow monitoring, building automation systems, HVAC control applications, and analog air velocity monitoring points where a 4–20 mA signal is preferred.
Can the AVU-2-A be mounted on a duct or wall?
Yes. Its compact design supports straightforward duct or wall mounting for suitable airflow monitoring applications.
Does GeneralTech Shop deliver the AVU-2-A across the UAE?
Yes. Call +971 6 5436933 to confirm availability and delivery timelines for your emirate.
Should I choose the AVU-2-A or AVUB-1-V?
The AVU-2-A provides a wider 0–1575 FPM range with a 4–20 mA output, while the AVUB-1-V covers 0–785 FPM and provides a 0–10 VDC output. Select the model based on your required measurement range and controller input.
