A Method of Calculation on Balance Resistance of Measuring Bridge in Strain Test

Abstract:

Considering the scattering difference in resistance of the strain gauge which will cause the bridge unbalance, the designers of strain measurement instrument have to add bridge-balance circuit into the design of measuring bridge in order to eliminate the problem of a DC component output caused by the unbalance. Thus, in the design of the bridge-balance circuit, the selection of balance resistances is of great significance. In this paper, through calculation analysis of the balance bridge, we obtained a couple of ideal values of balance resistances and tested them by experiments. In this condition, the experimental results have shown that the circuit has a great ability of regulation equilibrium. In brief, this paper provides the designers an effective method of choosing the balance resistances.
