DEVICE FOR DETERMINING THE POSITION OF A RAIL-GUIDED ELEVATOR CAR WITH A CODE SUPPORT

摘要

In order to determine the position of a rail-guided elevator car, the position transmitter device has a code support (9), which is mounted in a fixed manner on the guide rail (7) over the guideway and which is provided with code marks each having a different permeability. A constantly exact reading of the coding is ensured by virtue of the fact that the code support (9) is joined to a non-magnetic covering (15) in a fixed manner, whereby the code marks are covered toward the exterior by the non-magnetic covering (15). In an advantageous design, the code support (9) is inserted with the outwardly pointing nonmagnetic covering (15) into an accommodating slot (16) of the elevator car guide rail (7), whereby achieving a simple and reliable fitting and, in addition, preventing temperature-dependent expansion differences between the code support and the guide rail.
