ABSTRACT:
The invention relates to an apparatus for the contactless coupling of a suspended part 9, provided with a magnet 12 and located in a housing 6 to a force measuring device outside housing 6 and which is provided with a controllable electromagnet 1. Unlike in known apparatuses of this type, the position change of the suspended part 9 is recorded in absolute terms with respect to housing 6 and used for controlling electromagnet 1. This gives greater freedom in the design of housing 6, which can now be designed for a wider temperature and pressure range than hitherto, because no longer is it necessary to take account of a distance measurement through the housing wall.
