摘要: A position and motion transducer is described comprising means for providing a permanent magnetic field adjacent an appropriately oriented toroidal transformer, which can be either an isolation transformer or an autotransformer. The means for providing a permanent magnetic field, in an especially useful embodiment is a permanent magnet cobalt disk magnet with its surface pole facing generally radially in the plane of the torus or generally perpendicular the axis thereof. Appropriate excitation of one winding of the toroidal transformer enables readout equipment connected with the other winding to indicate the position and movement of the magnet relative the toroid. Appropriate mounting of the magnet enables various measurands to be indicated. For example, mounting the magnet on or for movement with a diaphragm enables fluid pressures applied thereto to be measured while mounting the magnet on a spring support force plate or piston/cylinder enables the force or weight applied thereto to be measured.
