Kriechfreier Folien Dehnungsmesstreifen durch Füllstoffanteil und Umkehrstellenverhältnis

摘要

A load cell is constructed with several strain gauges (7). Each of the strain gauges (7) is formed with a meandering conductive portion on a substrate or base member (8). Portions of the meandering conductive layer (9) defines a predetermined tab ratio. The base member (8) is formed with a predetermined amount of filler and the tab ratio is predetermined such that the creep characteristic of the strain gauge is substantially zero in a load cell having a generally low rated load.
