Abstract: Electron balance is widely used, and its sensor is easy attenuated by overload. In this article, the configuration and basic technique parameters of resistance strain sensor have been analyzed, as well as the failure phenomena for sensors attenuated by overload. Then the examine methods and some facility repair methods for the faults caused by overload are proposed. The practical results prove that many overloaded electron balances can be normally used with these maintain methods, and also, these methods can be technique references for those person who are verifying or maintaining electron balances.

Keywords: Electron balance; Sensor; Overload; Elastomer; Output voltage; Resistance
