Energy technology: wind power, generators, large motors
In order to ensure high efficiency in power plants and large motors, predictive maintenance is an essential factor. Therefore, very high requirements are placed on the sensors in terms of accuracy, reliability and compactness. Sensors from Micro-Epsilon have proved invaluable with regards to safe plant operation in the test bench and in high volume applications.
Mobile oscillation measuring system for wind turbines
Test, inspection and certification authorities offer mobile oscillation measuring systems for wind turbines without permanently installed Condition Monitoring Systems. They are used for prototype plants ...
Show detailsNoise reduction in wind turbines
Wind turbines generate environmentally friendly power, but are often rather unpopular with their residents in the neighborhood, as they also generate noise. One of the noise sources in wind turbines is ...
Show detailsOscillation measurement of the drive train in wind turbines
Oscillation of the drive train (rotor imbalance, overloading) exceeding the limit values may lead to a failure of components and plant parts. Prerequisite for early recognition of damage and for predictive ...
Show detailsMeasuring 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. ...
Show detailsRotor 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 ...
Show detailsMonitoring 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.
Show detailsMonitoring the tower oscillation
Wind turbines are exposed to oscillations and shock loads. In order to avoid damage and expensive downtime, these tower oscillations are monitored. When exceeding limit values, the plant is reliably shut ...
Show detailsRotor 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 ...
Show detailsAlignment of solar panels
Aligning solar panels in relation to the course of the sun increases the energy yield, and therefore the effectiveness of a solar panel. Only if the solar panels are always at an optimum angle to the sun, ...
Show detailsPosition monitoring when anchoring a tripod
In offshore wind turbines, tripods act as the foundation. INC5701 inclination sensors are used to monitor the alignment during the assembly process.
Show detailsSupporting 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 ...
Show detailsMeasuring 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 ...
Show detailsMeasuring 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 ...
Show detailsMeasuring 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 ...
Show detailsOil 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, ...
