The wind transmitter is intended for use in the wind energy, meteorology and environmental measuring technology. Primarily developed for position evaluation and measurement of power curves of wind turbines, the anemometer gathers the following measured variables: Horizontal component of the wind velocity, Absolute and relative air pressure, Inclination angle between the Z-axis and the vertical, Inclination angle between the X-axis and the horizontal, Inclination angle between the Y-axis and the horizontal, Frequency and acceleration in the X-, Y- and Z-axis, Housing interior temperature.

Further characteristics include a defined and optimized dynamic behavior even at highly intense turbulences, minimal over speeding, a low starting value and an optimized oblique inflow behavior.
An integrated compensation of the effect of the air density on the rotation velocity of the cup star distinguishes this sensor especially in its characteristics. There is a digital interface to the device in form of an RS485 interface in half-duplex mode. Together with the ID-based communication, the interface enables the operation of the wind transmitter in a bus. Two data protocols are available:

  • ASCII (THIES format).
  • Binary (MODBUS-RTU).

For operation in winter, the device can be equipped optionally with an electronically controlled heater which provides a hardly measurable friction moment of the ball bearings in low temperatures and prevents any ice build-up on shaft and on the gap.
