Safety device for lifting magnets |
摘要 |
A safety device for lifting magnet has sensor means responsive to flux produced by the device in the magnetic circuit including the body to be lifted, a transducer responsive to the lifting tension produced by the device together with a signal translation circuit effective to compare signals from the sensor and from the transducer and to provide an output indicative of a safety margin between lifting tension and the field available for lifting.
