Offset Measurement of the coupling ring

In wind turbines, at above 100 meters of height, enormous wind loads act on the rotor blades, housing and tower. This is why the gearbox and generator have an elastic bearing. In such condistions, it is important that the relative movement of the gearbox and generator are balanced in couplings in wind turbines. To determine the load profile, the offset of the coupling ring is measured using eddy current sensors to determine distance.

Eddy current displacement sensors by Bestech Australia are robust sensors designed for harsh ambient conditions and integrated in restricted installation spaces such as the the metallic coupling ring in this case. To determine the load profile, the measured values are monitored so as to avoid unnecessary wear of couplings, bearings and shaft seals or, any serious damage to the wind turbine. Eddy current sensors allow measurements to be taken in different directions – in the axial, radial and tangential axes.

These sensors have a compact design with integral controller. Measurements given by these sensors are stable and reliable which is irrespective of the pressure and temperature. These sensors persist an immunity against lubricants and vibrations that makes them stand out.
