Frequently Asked Questions

What is the Dwyer AVU air speed probe used for?

The Dwyer AVU air speed probe measures air velocity from 0–11 m/s and is ideal for HVAC, building automation, and environmental monitoring applications. It provides a 4–20 mA output with ±5% accuracy and an IP67 housing, making it suitable for demanding airflow measurement tasks in Singapore's industrial and commercial facilities.

What are the specifications of the Dwyer AVU-1-A air speed probe?

The Dwyer AVU-1-A air speed probe has a range of 0–11 m/s, a 4–20 mA output, ±5% accuracy, and an IP67 housing. It operates on 24 VDC power, has a maximum startup current of 85 mA, and a response time of 15 seconds typical. The probe dimensions are 19 mm x 240 mm and it weighs 250 g.

Where to buy the Dwyer AVU air speed probe in Singapore?

3G Electric supplies the Dwyer AVU air speed probe to customers in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on the AVU-1-A or other models in the series.

How to install the Dwyer AVU air speed probe?

To install the Dwyer AVU air speed probe, align the probe with the airflow direction as orientation is indifferent but alignment is required. Use the cable gland for 4–8 mm cable and connect the 4–20 mA loop to a 24 VDC supply. Ensure the IP67 housing is sealed properly for outdoor or dusty environments.
