Изобретение относитс к измерительной технике и может быть использовано в устройствах дл измерени и контрол различных величин, основанных на преобразовании измер емой величины в изменение индуктивности катушки.The invention relates to a measurement technique and can be used in devices for measuring and controlling various quantities, based on converting the measured value to a change in the inductance of a coil.
Известен .индуктивный измерительный преобразователь, содержащий магнитопровод и обмотку, расположенную на магнитопроводе Cl.,QKnown .inductive measuring transducer containing the magnetic core and winding located on the magnetic circuit. Cl., Q
Недостаток преобразовател состоит в погрешности измерени , вызванной изменением магнитного состо ни участков маг нитопровода под воздействием различных факторов., JThe disadvantage of the converter consists in the measurement error caused by the change in the magnetic state of the sections of the magnetic conductor under the influence of various factors., J
Наиболее близким по технической сущности к предлагаемому вл етс индуктивный измерительный преобразователь, содержащий магнитопровод с обмотками и генератор Г 2 .20The closest in technical essence to the present invention is an inductive measuring transducer comprising a magnetic core with windings and a generator G 2 .20
Недостаток этого преобразовател заключаетс в низкой точности измерений изза случайной величины остаточной намагниченности участков магнитопровода в момент выключени тока в обмотках и смещени градуировочной характеристики при повторном включении.The disadvantage of this converter lies in the low accuracy of measurements due to the random magnitude of the residual magnetization of the sections of the magnetic circuit at the moment when the current in the windings is turned off and the calibration characteristic is shifted upon re-activation.
Цель изобретени - повыщение точности измерений.The purpose of the invention is to increase the accuracy of measurements.
Указанна цель достигаетс тем, что индуктивный измерительный преобразователь , содержащий магнитопровод, обмотки, расположенные на магнитопроводе, и генератор , снабжен емкостью, источником посто нного тока и коммутатором, емкость подключена к входу коммутатора, первь й выход которого подключен к обмоткам, а второй - к источнику посто нного тока.This goal is achieved by the fact that an inductive measuring transducer containing a magnetic core, windings located on the magnetic core, and a generator, is provided with a capacitance, a direct current source and a switch, the capacitance is connected to the input of the switch, the first output of which is connected to the windings, and the second to source of direct current.
