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 % |
