Description

Разность сигналов CkU iU +uU лмеет место и при отсутствии градиента магнитного пол , так как создаетс  за счет неодинаковости коэффициентов преобразовани  , 5 2, феррозондов 1 и 2 и непараллельности их магнитных осей.The difference of the signals CkU iU + uU lmeet place in the absence of a magnetic field gradient, as it is created due to the difference in the conversion factors, 5 2, flux probes 1 and 2, and the non-parallelism of their magnetic axes.

Перва  составл юща  погрешности устран етс  подбором коэффициентов преобразовани , а также путем компенсации составл ющей магнитного пол , параллельной ос м феррозондов 1 и 2,The first component of the error is eliminated by selecting the conversion factors, as well as by compensating the component of the magnetic field parallel to the axes of the flux-probes 1 and 2,

В качестве компенсационного сигнала используетс  напр жение, снимаемое с одного из феррозондов (2) и усиленное усилительно-преобразовательной схемой 6.As a compensation signal, a voltage taken from one of the flux-probes (2) and amplified by an amplifier-converter circuit 6 is used.

Дл  компенсации другой составл ющей погрешности, пропорциональной напр женности магнитного пол , перпендикул рной к ос м феррозондов, используетс  дополнительна  обмотка 7, размещенна , например, на феррозонде 2 ортогонально его измерительной обмотке.To compensate for another component of the error, proportional to the strength of the magnetic field perpendicular to the axes of the flux-probes, an additional winding 7 is used, placed, for example, on the flux probe 2 orthogonal to its measuring winding.
