摘要
A measurement bridge circuit includes a first branch and a second branch. The first branch contains a first resistor which is sensitive to measured variables and an invariable resistor connected in series. A first tap point is located between the first resistor and the invariable resistor. The second branch contains a second resistor which is sensitive to measured variables and a variable resistor arrangement connected in series. The variable resistor arrangement includes a first component having an invariable electrical resistance value and a second component having a variable electrical resistance value. The second component is connected in parallel with the first component in order to vary a total electrical resistance value for the variable resistor arrangement. A second tap point is located between the second resistor and the variable resistor arrangement.
