| Abstract: | Metal foil strain wafer is a live strain component, through which the variation of lading condition is shifted. The resistance module can vary from resistance to voltage in proportion. We can place the strain wafers reasonably and compensate for the temperature according to the assemblage character of resistance module and improve the delication of it. |
