Applying the Wheatstone Bridge Circuit
This brochure provides you with concise knowledge about the application of Wheatstone Bridge Circuits.
In 1843 the English physicist, Sir Charles Wheatston (1802-1875), found a bridge circuit for measuring electrical resistances. In this bridge circuit, known today as the Wheatstone bridge circuit, unknown resistances are compared with well-defined resistances.
The Wheatstone bridge is also well suited for the measurement of small changes of a resistance and is, therefore, also suitable for measuring the resistance change in a strain gage (SG). It is commonly known that the strain gage transforms strain applied into a proportional change of resistance. ...
