CURRENT TRANSMISSION DEVICE FOR A FORCE MEASURING APPARATUS, IN PARTICULAR A WEIGHING APPARATUS
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. An electrical connection that has a low force shunt is provided in the housing for the two cables. The current transmission device (200) is embodied in such a way that it can be mounted in a housing (102) or externally on a housing (102) of the force measuring apparatus (100). In addition, the invention relates to a force measuring apparatus (100) having such a current transmission device (200).
