In the article are given theoretical and experimental evaluation of errors which arise due to incomplete suppression of common-mode noise on a differential sensor. The improved scheme of the measuring channel is suggested, its conversion feature studied and the possibility of diagnostic sensors is demonstrated. With using vector models evaluated the suppression of common mode noise for different pairs of transducer's parameters. Experimental confirmation of the theoretical estimates of possible levels of errors from common mode noise in the experimental measurement channels is given.
