Setting method of bridge and road coefficient for Dewetron data acquisition

The following chapter will briefly introduce the coefficient setting methods for different bridges and roads. For specific explanations, please refer to relevant articles. The following are the parameter definitions in the equation:

Ri... bridge strain gauge resistance

UD... bridge output voltage

UIN... bridge supply voltage

ε … Dependent variable

K... bridge road coefficient

ν … Poisson's ratio

One quarter bridge for measuring tension and compression

Half bridge for measuring bending

Full bridge for measuring bending
