WM80 has 2 analog outputs at 4–20 mA: wind speed and wind direction.
Select the configuration setting for the measurement value as sample, instant, or average depending on your application.
Both outputs reside at common output block that is isolated from the operating voltages, as well as from the device housing.
Measurement | Output range (mA) | Value range |
---|---|---|
Wind speed | 4.0–20.0 | 0–100 m/s (default) |
Wind direction | 4.0–20.0 | 0°–360° 4.0 mA= 180° 8.0 mA= 270° 12.0 mA = 0° (datum) 20.0 mA = 180° |
The analog output for wind speed extends below the range down to 3.8 mA and above the range to 20.5 mA. The scaling for the wind speed is configurable.
Analog output at 0.1–3.6 mA indicates device failure. The value is configurable (default 3.6 mA).
