PROBLEM TO BE SOLVED: To provide a rolling bearing device with a sensor including an arithmetic circuit part for measuring displacement of a rotor without contacting it to measure a load acting on the rotor, which is capable of instantaneously outputting only the actually acting load by avoiding the delay of processing of an arithmetic circuit required for elimination of a rotation-synchronous component.SOLUTION: Displacement of a rotor is measured by a rectangular coordinate system, and a measured signal is converted to a rotation coordinate system, and then, a signal of a rotation-synchronous component is extracted and is stored in a storage device, and the stored signal is used to perform an operation of eliminating the rotation-synchronous component. Further, a comparative operation device is provided which replaces the signal stored in the storage device with a signal of the latest rotation-synchronous component only in a prescribed case. |
