Abstract
Изобретение относитс к области магнитных измерений и может быть использовано в установках дл контрол магнитных свойств магнитом гких материалов в динамических режимах. Целью изобретени вл етс повышение точности измерени за счет исключени искажений формы намагничивающего тока и потерь в измерительной схеме. Ток источника 1 преобразуетс преобразователем 6 в напр жение, уровень которого ограничиваетс ограничителем 7 в зависимости от выходного сигнала задатчика 8. Затем это напр жение преобразуетс преобразователем 9 в ток, который поступает в токовую обмотку ваттметра 5. Измерительна схема не вносит фазовых искажений во всем рабочем диапазоне изменени намагничивающего тока. 2 ил.The invention relates to the field of magnetic measurements and can be used in installations for monitoring the magnetic properties of magnetically soft materials in dynamic modes. The aim of the invention is to improve the measurement accuracy by eliminating distortion of the form of the magnetizing current and losses in the measuring circuit. The current of source 1 is converted by converter 6 into a voltage, the level of which is limited by limiter 7 depending on the output signal of setpoint 8. Then this voltage is converted by converter 9 to current that flows into the current winding of the wattmeter 5. The measuring circuit does not introduce phase distortions in the whole working range of magnetising current. 2 Il.
