The two-voltage-output circuit called a double-current bridge is presented. A single DC current source is switched over and connected in turns to opposite arms of the four-element bridge circuit. The output voltages are dependent on the arm resistance increments and their values are given in absolute and relative units. The simplified signal conditioning formulas of strain and temperature simultaneous measurement of a cantilever beam are featured. The results achieved with the use of the circuit are also published.The accuracy measures (actual errors, limited errors and standard uncertainties) of the bridgetransfer functions are described.
