ABSTRACT:
In the rolling bearing device with a sensor in this invention, a band-shaped film111having insulation property is affixed to an outer circumferential surface of an outer ring101so as to extend in the circumferential direction. On the film111is affixed a foil112composed of identical four portions and having electrical conductivity which are placed at generally equal intervals in the circumferential direction of the outer ring101. A resistance between a first place and a second place of the foil112is measured by a resistance measurement section of a microcomputer. A preload calculation section of the microcomputer, upon reception of an output from the resistance measurement section, calculates a preload of the outer ring101based on the measured resistance.
