Abstract

Condition monitoring a cage to detect cage damage by detecting if a conducting material applied to a cage is unbroken or broken. The basic principle of the invention is to integrate a completely passive LC circuit, having the conductive material, on the cage. The LC circuit is magnetically activated and it is externally detectable when conducting material is unbroken or broken. The conducting material of the passive LC circuit is easily broken or worn, being weaker than the cage material. The cage material is non-metallic, such as a polymer material or other suitable synthetic materials.
