The WMT704 wind sensor extends the measurement range of the WMT700 series to 90 m/s. To get WMT704, you must place an order. Older versions cannot be upgraded to WMT704 in the field.
The WMT700 series offers the following measurement ranges:
| Model | Measurement range | Reporting range |
|---|---|---|
| WMT701 | 0 … 40 m/s | 0 … 50 m/s |
| WMT702 | 0 … 65 m/s | 0 … 75 m/s |
| WMT703 | 0 … 75 m/s | 0 … 100 m/s |
| WMT704 | 0 … 90 m/s | 0 … 100 m/s |
When the wind speed exceeds the measurement range, WMT700 gives an alarm. The sensor shows the measurement, but the accuracy is unspecified.
| Range | Accuracy |
|---|---|
| 0 … 75 m/s | ±0.1 m/s or 2 % of the reading, whichever is greater |
| 75 … 90 m/s | ±5 % |
