Abstract
A measurement module for monitoring an operating condition of a roller bearing having a first bearing ring and a second bearing ring rotating with respect to each other around a rotation axis comprises an energy harvesting device operable to generate energy from a relative movement between the first and second bearing rings and at least one deformation sensor operable to provide a deformation signal indicative of a deformation of a surface region of one bearing ring of the first and the second bearing rings. The deformation sensor is powered by the energy harvesting device. An evaluation circuit is operable to determine, using the deformation signal, a strain signal indicative of a present load on the bearing. The evaluation circuit is powered by the energy harvesting device and a common housing encloses the energy harvesting device, the deformation sensor and the evaluation circuit.
