- Abstract:
- A four-terminal (4T) bridge circuit unconventionally supplied by two current sources connected in parallel to opposite arms, named double current bridge (2J) is presented. It has two different outputs from both diagonals. Their output voltages are described as functions of arm resistances and their increments from the bridge balance in relative units are given. Example of its application in two-parameter simultaneous (2D) measurements of the strain and temperature is presented. Formulas of their signals and details of the designed conditioning circuit are given. Some results of experimental verification of this instrumentation are shortly mentioned.
