Description
UA‑1™ is an ultrasonic anemometer that provides both wind speed and wind direction in a digital, smart wind sensor.
UA‑1 can be installed on Dyacon MS‑100 series weather stations.
This Modbus sensor can also be used independently for industrial applications and can be connected directly to PLCs, SCADA equipment, and DCS to directly add environmental data for other automation and logging applications.
Feature Summary
- Wind speed (3 s, 2 min avg, and 10 min avg)
- Wind direction (3 s, 2 min avg, and 10 min avg)
- Rolling maximum wind speed and direction capture
- No bearings or moving components
- No wind direction dead spots
- Modbus RTU
- Low-power operation
Key Features
Construction
UA-1™ is made of machined acetal and nylon 12.
Mechanical construction minimizes snow accumulation.
Wind Direction and Speed
The wind direction and wind speed are detected using ultrasonic technology.
Mounting
The mounting tube fits over standard 3/4” pipe (IPS, SCH40), actual pipe OD 1.05″ (26.7 mm).
Data Connection
Power and data are supplied through a 4-wire connection. UA‑1 wind sensor uses a Modbus RTU slave interface.
