Abstract
A system that includes a driving component, such as a motor, and a driven component. The system also includes a torque limiter positioned between the driving component and the driven component. The driving component is coupled to a driving end of the torque limiter and the driven component is coupled to a driven end of the torque limiter. The torque limiter is configured to assume a normal operating state with no slippage between the driving and driven ends of the torque limiter and an over-torque operating state with slippage occurring between the driving and driven ends of the torque limiter. The torque limiter includes a metal moving part that assumes a first position when the torque limiter is in the normal operating state and a second position different than the first position when the torque limiter assumes the over-torque operating state. An inductive proximity sensor monitors the position of the metal moving part.
