Abstract
An inspection device comprises movable equipment (6) driven relative to a stand (7) and fitted with at least one inspection gauge (14, 15). The device also includes a measurement system (30) comprising a contactless transceiver system (30a) for emitting and receiving a light beam (F) along a path in which there is arranged a target (30b) that is securely mounted to the first inspection gauge, the transceiver system being secured to the stand, and delivering measurements continuously of the position of the first inspection gauge relative to the stand (7). A processor unit (31) is provided that means for detecting when the measurements of the position of the inspection gauge delivered by the transceiver system (30a) cease varying, in order to determine that contact has occurred between the inspection gauge and the container.
