PROBLEM TO BE SOLVED: To provide a rolling device sensor capable of improving the reliability in sensing of a detection element by detecting improper operation of the detection element. SOLUTION: This rolling device sensor 10 has a rolling bearing, a ball screw, and the detection elements 11, 12 detecting an operation condition of a rolling device such as a linear guide. Abnormality of the detection elements 11, 12 is detected by processing output signals from the detection elements 11, 12. COPYRIGHT: (C)2004,JPO
