The wind transmitter is designed for the acquisition of the horizontal component of the wind velocity in the field of meteorology and environ- mental measuring technology, evaluation of location, and measurement of capacity characteristics of wind power systems. In the plain country the wind transmitter meets all requirements of IEC 61400-12-1 for an Instrument of the accuracy class 0.5.Special characters are a defined and optimised, dynamic behaviour also at high turbulence intensity, minimal over-speeding, and a low starting value.The measuring value is available at the output as digital signal. It can be transmittedto display instruments, recording instruments, data loggers as well as to process control systems.
