Изобретение относитс к области измерительной техники, а .именно к устройствам измерени влажности твердых материалов методом спинового эха дерного магнитного резонанса (ЯМР). The invention relates to the field of measurement technology, and, in particular, to devices for measuring the moisture content of solid materials by the method of spin echo magnetic resonance (NMR).
По основному авт.св. 661323 известный импульсный протонно-резонансный влагомер, содержащий программатор, генератор радиочастотных импульсов, колебательный контур с исследуемым образцом, размещенный в зазоре посто нного магнита, приемник сигналов спиновых эхо, регистратор, пороговое устройство с заданным уровнем порогового напр жени , блок управлени и 15 логическую схему, причем выход приемника сигналов спинового эха соединен через пороговое устройство со входом блока управлени и через логическую схему - со входом регистрато- 20 ра, выход программатора соединен со счетным входом блока управлени , у которого один выход подключен ко входу программатора, а три других - к управл ющим входам логической схе- 25According to the main auth. 661323 a well-known pulsed proton-resonance moisture meter containing a programmer, a radio frequency pulse generator, an oscillating circuit with a test sample, placed in a constant magnet gap, a spin echo signal receiver, a recorder, a threshold device with a predetermined threshold voltage level, a control unit and 15 logic circuit and the output of the receiver of the spin echo signals is connected through a threshold device to the input of the control unit and through a logic circuit to the input of the recorder 20, the output of the programmer oedinen counting input with the control unit, which has one output connected to the input of the programming, and the other three - to the control inputs of the logic scheme 25

с помощью данного устройства влажность твёрдых материалов определ ют по величине.начешьной амплитуды А, пропорциональной количеству протонов. ЗОWith this device, the moisture content of solid materials is determined by the magnitude of the significant amplitude A proportional to the number of protons. ZO
воды, по двум измеренным амплитудам сигналов спинового эха ЯМР. При этом, дл устранени погрешности от протонов твердого водородсодержащего вещества на результаты измерени предварительно устанавливают уровень по ,рогового напр жени Up таким,чтобы измерение амплитуды сигналов спиновых эхо , и принадлежали только составл ющей от протонов воды.water, by the two measured amplitudes of the spin echo signals of NMR. At the same time, in order to eliminate the error from the protons of the solid hydrogen-containing substance, the measurement results are preliminarily set by the horn voltage Up such that the amplitude of the spin echo signals is measured and belongs only to the component of water from the protons.
