摘要： A device and method for effectuating the temperature compensation testing of digital load cells. The device uses conductive heat transfer to establish and maintain the temperature of the load cell(s) during testing. The device may include a vessel into which one or more load cells to be tested are placed. Temperature control of the load cells may be accomplished by circulating a temperature controlled fluid through the vessel. The vessel containing the one or more load cells may then be placed in a load application device that applies a load(s) to the one or more load cells during testing. Readings from the one or more load cells are used to establish a temperature compensation factor for each load cell tested. In other embodiments, temperature control of the load cells may be accomplished by placing the load cells in contact with a solid heat transfer element(s).

摘要： A force-measuring cell is disclosed which is equipped with a force transducer which includes a deformable body that is equipped with sensors. The deformable body connects a housing-mounted fixed part to a force-introducing part of the force transducer. The sensors are connected to electrical conductors of at least one flat ribbon cable which leads to a circuit module that serves to process the measuring signals and contains the connections for joining the sensors together in a measuring bridge circuit. The conductor tracks can be configured so that all of the connecting leads from nodal points of a measuring bridge to the contact terminals of the sensors have at least approximately equal resistance values.

摘要： An exemplary mounting arrangement serves for the mounting of a force transducer that has a sensor-equipped core part connecting a support part to a force-application part. The support part can be bolted to a fastening part by mounting screws, and the force-application part can be bolted to a weighing pan carrier by means of mounting screws. The support part and the force-application part of the force transducer can each have a triplet of threaded holes serving to receive the mounting screws. Each triplet forms an isosceles triangle whose apex points towards the deformable body. The symmetry axes of the triangles lie in a plane that is parallel to the displacement travel of the force transducer. The mounting arrangement can be further configured to provide an effective overload protection in a low-profile design and to provide a thermally uncoupled fixation.
