A single DC current source (J) is switched over and connected in turns to opposite arms of the four-element bridge circuit. This two-output circuit with two voltage outputs is called a double current circuit (2x1J). The output voltages are differently dependent on the arm resistance increments and their values are given in absolute and relative units. An original application with two sensors acting as strain gauges and RTD’s is presented. Signal conditioning formulas of 2D measurement of deflection and temperature of a cantilever beam are discussed in detail. Some results achieved with the use of the circuit are presented, as well.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eee.21.1.6834">http://dx.doi.org/10.5755/j01.eee.21.1.6834</a></p> ER -
