Abstract
A sensor devicehas a magnetostrictive sensorprovided on a fixed-side raceway memberfor detecting a gap between the sensor and a rotation-side raceway memberand means for processing the output of the magnetostrictive sensorThe processing means comprises a rotation detecting unit for determining the speed of rotation of the rotation-side raceway memberfrom the number of repetitions of a variation in the output of the magnetostrictive sensora unit for averaging output values of the magnetostrictive sensorand a load calculating unit for determining the load acting on an antifriction bearing from the output averaged by the averaging unit.
