UNDERESTIMATED IMPACT OF MEASURING CABLES ON HIGH-PRECISION CARRIER FREQUENCY AMPLIFIER RESULTS AND COMPENSATION METHODS THEREFOR

Marco M. Schäck
Abstract:
The resolution when acquiring transducer results is physically limited. To ensure accurate measurements of resistive transducers in full bridge circuitry, in addition to the amplifier's precision, the use of appropriate measuring cables and their proper connection are very important.
Sources of errors with respect to the used measurement cables and their compensation to achieve the high accuracy class are shown. If these principles are not observed, there will be inescapably significant errors.
