Patent ID: 7928743

Claim:
A measuring bridge arrangement, comprising: a measuring bridge with four resistive elements, at least a first supply terminal, a first measuring signal terminal, a second measuring signal terminal and a test tap, wherein measurement signals dependent on properties of at least one resistive element of the measuring bridge can be tapped at the test tap of the measuring bridge in each of four different states of operation; and a working point adjustment circuit to bring the measuring bridge into the four states of operation and defining different working points of the measuring bridge, wherein, in a first state of operation, the working point adjustment circuit feeds the measuring bridge via at least the first supply terminal, wherein, in a second state of operation, the working point adjustment circuit feeds the measuring bridge via the first measuring signal terminal, wherein, in a third state of operation, the working point adjustment circuit feeds the measuring bridge via the second measuring signal terminal, and wherein in a fourth state of operation, the working point adjustment circuit feeds the measuring bridge via at least the first supply terminal and wherein a shunt element providing for a current path in parallel to one of the four resistive elements of the measuring bridge is activated.
