PCT No. PCT/DE95/01842 Sec. 371 Date Jul. 2, 1997 Sec. 102(e) Date Jul. 2, 1997 PCT Filed Dec. 22, 1995 PCT Pub. No. WO96/21841 PCT Pub. Date Jul. 18, 1996A travel sensor (10) is proposed which has a insertion body (11) consisting of non-ferromagnetic material with good conductive properties. The insertion body (11) is submerged into a measuring coil (15) through which alternating current flows. In addition, the travel sensor is enveloped by a shielding sleeve (16) consisting of ferromagnetic material. Due to the alternating effect between the magnetic field of the coil (15), through which an alternating current flows, and the two materials, at designated frequencies of the alternating current and the respective volume of the insertion body (11) or the shielding sleeve (16), it is possible to compensate the effects of the temperature in such a way that at varying temperatures the measuring curves of the travel sensor (10) extend nearly parallel across the entire measuring range. |
