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