    摘要： A device for signalling the presence of a pig in a pipeline (5) comprises a housing (2) sealingly connetected over an opening (6) in a pipeline wall, an actuating member (7) extending through the opening (6) and displaceable inwardly of the housing (2) by a passing pig. The member (7) mounts a first magnet (12). A signalling member (16) is mounted externally of the housing for movement between a normal position and a signalling position in which it provides a visual indication of the passage of a pig. A second magnet (30) is mounted to the member (16) and is arranged to be repulsed by the first magnet upon inward displacement thereof into the housing so that the member is moved to its signalling position.
