  • Patent number: 11221250
    Abstract: An electromagnetic force-compensation direct measuring system (100) has a load receiver (101), which is connected to a force-compensation device (120) via a power-transmission linkage. The system has a multipart parallel guide mechanism, which has at least two parallel-guiding members (131, 132) spaced apart by the power-transmission linkage. The force-compensation device has at least one permanent magnet (121) and a coil (122) electrically connected to a controllable electrical circuit. At least one parallel-guiding member is electrically integrated in the controllable electrical circuit. The power-transmission linkage is designed as a single-part coil body (110) such that the coil is arranged on the coil body between the parallel-guiding members and is electrically connected to the controllable electrical circuit.
    Type: Grant

  • Patent number: 8426753
    Abstract: A gravimetric measuring instrument that contains a weighing cell having a load-transmitting member. A load receiver can be coupled to the load-transmitting member through a releasable connection. A mechanical stop resides on the load-transmitting member, and a mechanical counter stop resides on the load receiver. By means of an eccentric bolt engaging the load receiver and the load-transmitting member, the mechanical stop can be pressed against the mechanical counter stop, whereby the stop can be clamped tight against the counter stop. With this arrangement, the load receiver can be rigidly but releasably secured to the load-transmitting member.
