Dwyer AVUL‑5DA1 Air Velocity Sensor – Accurate Airflow Measurement Solution
The Dwyer AVUL‑5DA1 is an air velocity transmitter providing 4–20 mA or 0–10 VDC analog output, ideal for HVAC systems, cleanrooms, factories, and smart buildings. The device is imported and officially distributed by DLK TRADING SERVICE COMPANY LIMITED, ensuring authentic CO/CQ documentation and professional technical support.
Operating Principle
The Dwyer AVUL‑5DA1 measures airflow using a precision probe, converting airflow directly into a proportional analog signal. Its robust design, rated NEMA 4X / IP66, allows installation in HVAC ducts or light industrial environments without interference from dust or moisture. (see detailed AVUL‑5DA1 product)
Practical Applications
The Dwyer AVUL‑5DA1 is widely used due to high accuracy and easy analog integration:
-
Monitoring airflow in central HVAC systems, AHUs, FCUs, and VAV units.
-
Controlling airflow in cleanrooms, hospitals, and operating rooms to maintain air pressure and environmental quality.
-
Tracking airflow in factories, warehouses, exhaust systems, or paint booths.
-
Integrating with building management systems (BMS) to optimize energy efficiency and trigger automatic alerts for abnormal airflow.
