An electromechanical coupling system for preventing a mechanical device from operating beyond preselected operating parameters or control parameters.

摘要

An electromechanical coupling system for operating a mechanical device within preselected parameters comprises a sensor means (2) which generates control pulses corresponding to the operating parameter sensed, electronic control unit (4) which is connected to the sensor means electrically and generates enabling pulses in proportion to the control pulses only when the operating or control parameter of the mechanical device is within the preselected values and a coupler means (6) locatable between a drive unit (20) and a driven unit (22) of the mechanical device for decoupling the drive unit from the driven unit when the enabling pulse is suppressed and coupling them together when the enabling pulse is present.
