Abstract
A support member extending outwardly from the surface of a bearing overlies a rotatable shaft supported by the bearing. The support member is spaced a preselected distance from the shaft, and a plurality of sensors for detecting displacement of the shaft extend from the support member toward the shaft. Each sensor is positioned on the support member a preselected distance from the surface of the bearing. A probe extends from each sensor to a fixed distance from the shaft. Control means are electrically connected to each sensor and receive signals proportional to the shaft dynamic displacement therefrom. In response to shaft displacement the sensors generate displacement signals which are converted by the control means to a readout representative of the dynamic force applied by the shaft to the bearing.
