A four-terminal (4T) bridge-circuit with a current source connected in parallel to opposite arms, is presented. This two-output circuit is named a double current bridge. The example of its application is presented. Signal conditioning formulas of two-parameter measurement of strain and temperature are discussed in detail. An advantage of this solution is that temperature compensation is done without any additional temperature sensor. Some results achieved with the use of this bridge-circuit are briefly described. The standard uncertainties of strain measurement and temperature measurement have been calculated.
