  • Patent number: 7042223
    Abstract: A method of inspecting a conduit and a conduit inspection device are disclosed. The method relates to producing a primary magnetic field to induce a current in the conduit so that the currents produce a decaying secondary magnetic field influenced by the conduit. The secondary magnetic field is analysed by time domain analysis to provide an indication of the state of the conduit. The device which produces the primary magnetic field can be moved relative to the conduit so that the secondary magnetic field is detected at different positions along the conduit so that the state of the conduit at various positions along the conduit can be determined. The device for producing the primary magnetic field comprises a transmitter having at least one winding and a detector for detecting the secondary magnetic field comprising at least one inductor coil. A storage is provided for storing the data detected by the inductor coil and is coupled to the conductor coil by a communication link.

  • Publication number: 20040027129
    Abstract: An inspection system is disclosed. The inspection system comprises a transmitter and a receiver configured for communication with a remotely positioned processing means. The transmitter and receiver are arranged as a mobile apparatus configured for insertion into any duct, conduit, pipeline, mining shaft, or the like, or any diameter or cross section. The transmitter is configured to transmit an electromagnetic signal to induce an electromagnetic response in the duct and the electromagnetic response is detected by the receiver. The mobile apparatus is self-powered and processes the electromagnetic response prior to communicating the processed response to the remotely positioned processing means as a discrete signal.
