Abstract:
A load cell that includes a beam extending from a fixed section to a load section including a deflection section that moves under a load and a central beam section spaced from the deflection section. At least one strain gauge is coupled to the beam for detecting movement of the beam. A stop element including a bearing surface is also provided and coupled to the beam and configured such that the bearing surface does not engage the beam in a first position and engages the beam in a second position.
