The First Class Advanced X modelThies Clima has introduced a new model of its First Class anemometer. By releasing the new version of the international standard IEC61400-12-1 Ed.2.0 2017-3, which describes more sophisticated and dedicated anemometer classification and calibration methodology, an improvement and adaptation of the instruments in respect of the changed requirements became essential.

The First Class Advanced X model, comes also with additional new capabilities. Beyond the expected wind speed measurement, the sensor measures temperature, pressure, vibration and acceleration and provides all readings via the RS485 serial interface. To achieve best accuracy and classification results the wind speed readings can be pressure compensated by use of the internal pressure sensor. In the internal memory of the First Class Advanced X, the calibration results are stored for tracing of the instrument history over its entire lifecycle.
