Abstract (en)
[origin: WO9621159A1] A transducer device for measuring the linear displacements of a monitored body. The device includes two stationary plates (1, 2) and a movable plate (6). The device further includes a mechanism (4) for applying an input alternating tension to one of the pair of stationary plates (1, 2) and a mechanism (16, 17, 20) for connecting the movable plate (6) to the monitored body so as to cause the displacement of the movable plate (6) to be a function of the displacement of the monitored body. The device further includes a mechanism (5) for monitoring the current induced in one of the stationary plates (1, 2). One of the stationary plates (1) and the movable plate (6) constitute a first capacitance while the other stationary plate (2) and the movable plate (6) constitute a second capacitance. The pair of stationary plates (1, 2) constitute a third capacitance. At least one of the first and second capacitances are a function of the displacement of the movable plate (6) and therefore of the displacement of the monitored body.
