Abstract
A magnetic field source is mounted on one race of a two-race radial or thrust bearing. The race with the magnetic field source rotates. The other race does not rotate. A magnetic field sensor is mounted on a flexible arm of a rigid arm support. The arm support with its flexible arm does not rotate but the flexible arm may flex in response to movement of either of the races or the flexible arm support member so that the magnetic field sensor is always kept a constant predetermined distance from the magnetic field source. The number of times alternate magnetic poles on the rotating race is sensed by the sensor per unit of time indicates the speed of the rotating race.
