Abstract
A compensating bridge circuit is used for measuring physical quantities dctly. The circuit comprises an unbalanced Wheatstone bridge having a quantity-dependent voltage at an output thereof. An ohmic potential divider circuit produces a divisional voltage for compensating the quantity-dependent voltage. The divider circuit includes two resistances one of which is variable. An input voltage is fed to the Wheatstone bridge and a supply voltage is provided to the potential divider circuit. The supply voltage is composed of the bridge input voltage and the divisional voltage whereby, when the circuit system is balanced, the relationship between an input quantity x and a balancing quantity y is linear.
