Abstract
A system for sensing a pipe joint within a well structure bore comprises a body connectable in line with the well structure. The body has a central bore therethrough and includes a plurality of blind bores extending radially inwards from the outer surface. The system further includes at least one sleeve being locatable within one of the plurality of blind bores wherein each of the sleeves has a magnet located at an end thereof at least one sensor being locatable within one of the at least one sleeves. The at least one sensor is operable to output a signal representing the width of a metallic object located within the central bore. The system may further include a display operable to receive the output signal from the at least one sensor and to display an output to a user indicating the width of the metallic object within the central bore.
