A dsplacement transducer includes two permanent magnets, a flux-gate meter and two gradient meters placed in the inter-pole gap of same poles of permanent magnets. The first and the second pairs of flux-gate meters are used, those are displaced one with respect to another by distance equal to the length of the inter-pole gap and the length of the permanent magnet, at that the output windings of the flux-gate meters of each of the pairs are connected in differential circuit, and the ends of the output windings of the flux-gate meters placed at one side of the permanent magnets are connected. |
