Abstract (en)
[origin: FR2793317A1] The invention concerns a device for measuring the position of a lower positioning reference system (130) with respect to an upper positioning reference system (110) located above the former comprising a pendulum (150) including a pendulous mass (152) and a metrological wire (154) fixed on one side to the pendulous mass and on the other to the higher reference system, and a first proximity sensor (160) capable of supplying a signal representing the position or the variation of position in the vertical direction of a planar zone (158) of the surface of the pendulous mass relative to the lower reference system. Second (170) and third (190) proximity sensors, both optional supply each a signal representing the position or variation of position of a zone of the wire (154) relative to the two planar vertical surfaces of measurement related to the lower reference system and perpendicular to each other.
