Abstract :
The contradiction between widening the frequency range (FR) and rising the flat part of transfer function (TF) of an induction magnetic field transducers (IT) device while maintaining steady operation is solved by deducing the stability conditions and, finally, the informational and metrological characteristics are stated. Such stability limits are proposed as the relationship of IT circuit values with positive and negative magnetic flux feedback loops. The basic metrological characteristics for five wide-band IT modes are formulated. The steady function of these modes is ensured by satisfying simultaneous inequalities. Such characteristics are in a state of flux in the FR from <0.1 Hz to >10 MHz and the TF up to 500 Vm/A. In addition, we propose the informational capability index of ITs as FR and TF generalization and also the establishment of a precise upper frequency limit.
