Abstract: The invention relates to current transmission device for a force measuring apparatus, in particular a weighing apparatus, wherein the force measuring apparatus (100) has a housing (102) and a base region as well as a moveable region. The current transmission device has a pressure-resistant housing (202), which can be fixedly connected mechanically to the base region of the force measuring apparatus (100), and a connecting element (216), which, at an outer end region that protrudes from the housing (202), can be fixedly connected mechanically to the moveable region of the force measuring apparatus (100) in an operating state. In an operating state, the connecting element (216) passes through the housing wall (208) in a contactless and ignition-safe manner. The connecting element (216) is embodied as a moveable cable pass-through and directs a first cable (220) into the interior of the housing. A housing-affixed cable feedthrough (206) directs a second cable into the interior of housing.

Abstract: A method for optimizing the running properties of a rotating belt of a weighing belt conveyor includes, for at least one rotation of the belt, determining a unique reference position on the belt. A force signal is determined in dependence on the movement of the belt with respect to the reference position during the at least one rotation. From this force signal, the course of a deviation of the force signal from a set value as a consequence of a disruptive force is determined. At least in correspondence with the direction of the determined deviation, the mass of the belt is increased or reduced at locations in dependence on the position of the belt with respect to the reference position.
