Beschreibung
Zusammenfassung:	A sealing bolt includes a seal head adapted to be mounted to the container lid, a seal stud adapted to be mounted to the container body, a pin connecting the seal head to the seal stud, a conductor in a transverse passage in the pin and a resilient member arranged for biasing the pin into a first position in which the conductor is compressed. The pin is movable against biasing by the resilient member into a second position by application to the seal head of a predetermined torque. The sealing bolt also includes a monitoring and detection unit including a transmitter and a detector coupled to respective ends of the conductor, and a processor coupled to the transmitter and the detector operable to determine that the pin has been moved into the second position for a first time when a signal detected by the detector has undergone a predetermined change.
