Vorrichtung zur Ermittlung der Lage einer mit einem elektrisch diskontinuierlich leitenden Band umgebenen rotierenden Stahlwelle sowie Verfahren zur Herstellung des Bandes. |
摘要 |
The device for determining the position of a rotating steel shaft (1) comprises an eddy current sensor and a band (3) moving past the sensor. The band is attached firmly to the shaft and consists of a strip (4) of insulating material having areas covered with a non- ferromagnetic material possessing a good electrical conductivity, these areas being distributed regularly around the shaft. Characteristically, the strip (4) is stuck on to the shaft (1) by the side carrying the areas of non-ferromagnetic material. <??>The device is very simple and gives a very large-amplitude signal. <IMAGE> |
