Description

Известные приборы радиоактивного действи  дл  определени  содержани  серы в нефтепродуктах имеют р д недостатков. Работа с этими приборами затруднена из-за необходимости строгой фиксации времени измерени  по секундомеру, а кроме того, приборы требуют периодического эталонировани , так как в них применены счетчики Гейгера, которые в процессе эксплуатации стареют. Эти недостатки значительно снижают точность результатов анализа.The known radioactive devices for determining the sulfur content of petroleum products have several disadvantages. Working with these devices is difficult because of the need for strict fixation of the measurement time by a stopwatch, and in addition, the devices require periodic calibration, since they use Geiger counters, which are aging during operation. These shortcomings significantly reduce the accuracy of the analysis results.

Предлагаемый прибор обеспечивает автоматическое определение содержани  серы в нефтепродуктах с высокой точностью, что достигаетс  наличием мультивибраторов дл  получени  логарифмической характеристики шкалы прибора и устройства дл  периодического автоматического эталонировани .The proposed instrument provides automatic determination of the sulfur content in petroleum products with high accuracy, which is achieved by the presence of multivibrators to obtain the logarithmic characteristic of the instrument scale and the device for periodic automatic calibration.

Определение содержани  серы в нефтепродуктах производитс  по степени поглощени  у-излучени  от источника 1 (см. блок-схему) и отопа Fe в кювете 2 с нефтепродуктом. Излучение регистрируетс  счетчиком 3 Гейгера (МСТ-17). Устройство 4 дл  автоматического эталонировани  периодически помещает перед счетчиком 3 эталонный источник 5 излучени  так, что 15 сек на счетчик попадает излучение от эталонного источника, а следующие 15 сек - излучение проход щее через кювету.The determination of the sulfur content in petroleum products is made by the degree of absorption of γ-radiation from source 1 (see the block diagram) and heating of Fe in a cuvette 2 with petroleum product. Radiation is recorded by a Geiger counter 3 (MST-17). The automatic calibration device 4 periodically places a reference radiation source 5 in front of the counter, so that 15 seconds radiation from the reference source enters the counter, and the next 15 seconds - radiation passing through the cell.

Канал регистрации излучени  состоит из счетчика 3, усилител  6, трех мультивибраторов 7, 8, 9, образующих логарифмическое устройство . Посто нный потенциал на выходе устройства, пропорциональный логарифму частоты следовани  импульсов, усиливаетс  усилителем 10 посто нного тока, собранным по мостовой схеме. Эталонирующее устройство 4 подключает канал регистрации излучени  к усилителю 10 так, что сигналы, соответствующие эталонному излучению, попадают на одно плечо моста, а сигналы, соответствующие излучению , прошедшему через кювету, - на другое.The radiation detection channel consists of a counter 3, an amplifier 6, and three multivibrators 7, 8, 9, forming a logarithmic device. A constant potential at the output of the device, proportional to the logarithm of the pulse frequency, is amplified by a DC amplifier 10 assembled in a bridge circuit. The reference device 4 connects the radiation detection channel to the amplifier 10 so that the signals corresponding to the reference radiation fall on one side of the bridge, and the signals corresponding to the radiation transmitted through the cell are on the other.
