The idea with alternately switched current sources allows to measure simultaneously small (up to 1 Ω) differences and sums of two changes in resistance taken from a pair of sensors plugged in the circuit. Problems relating to circuit realization and a way of signal processing are discussed. In the prototype transducer shielding and filtering RFI/EMI were used. The results of measurements conducted with the use of precision resistance decade boxes are presented.</p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.eie.23.5.19268">http://dx.doi.org/10.5755/j01.eie.23.5.19268</a></p> ER -
