Measuring the bearing gap in wind turbines

To date, bearing gaps were measured during standstill based on a tactile principle. Therefore, long inspection intervals were required, which in turn, may increase the risk of a complete plant failure. ...

Alignment of solar panels

Aligning solar panels in relation to the course of the sun increases the energy yield, and therefore the plant effectiveness. Inclination sensors ensure that the panels are always properly aligned.

Rotor stress tests in the test bench

Test rigs have been developed for load tests on wind turbine rotor blades and simulate the real loads caused by high winds and weather. The tip of the rotor blade can be distorted by up to 10m due to mechanical ...

Rotor gap measurement in the generator

In order to monitor rotor behavior in the generator, capacitive displacement sensors measure the gap between stator and rotor. Despite high temperatures and electromagnetic fields, capacitive sensors from ...

Monitoring the air flap openings

In order to control air supply, the air flaps automatically open and close depending on the temperature. Draw-wire displacement sensors monitor the position of the open air flap.

Monitoring the tower oscillation

Acceleration sensors are used in wind turbines in order to monitor the tower oscillation. When the oscillation is too strong, the rotor blades are removed from the wind.

Supporting moments of the nacelle

In order to monitor the supporting moments, eddy current displacement sensors measure the distance between the nacelle and the tower, which enables early recognition of any oscillations. Therefore, the ...

Measuring the foundation movement

Laser triangulation sensors measure the distance from the foundation in order to detect the tower movements. High measuring rates enable to detect vibrations directly. Depending on the number of sensors ...

Measuring the deflection of the clutch disc

Eddy current displacement sensors measure the axial, radial or tangential deflection of the clutch disc. These robust sensors are designed for harsh ambient conditions and, due to their extremely compact ...

Measuring the temperature of frictional heat on bearings

The gearbox temperature in wind turbines is measured continuously during operation. Heating up of components may indicate a potential problem with a component. If a certain threshold is exceeded, subsequent ...

Oil gap measurement in shafts

With regard to predictive maintenance, the oil gap should be measured, i.e. the distance between the bearing surface and the shaft filled with lubricants. Despite pressure, high temperatures and lubricants, ...
