Abstract
Disclosed is a device for estimating a load in a bearing, including a receiving unit for receiving a sensor signal waveform. The sensor signal waveform is provided by at least one sensor probe arranged at the bearing. The at least one sensor probe is configured to measure a displacement and/or strain of the bearing. The sensor signal waveform is a product of a carrier waveform and a load waveform, and an electronic control unit configured for processing the received measured sensor signal waveform, by determining a rolling element frequency from the measured sensor signal waveform, determining the carrier waveform based on the determined rolling element frequency and the measured sensor signal waveform, determining the load waveform based on determined carrier waveform and the measured sensor signal waveform, and estimating the load in the bearing from the determined load waveform.
