Изобретение относитс к области измерительной техники.The invention relates to the field of measurement technology.
Известные способы определени влажности исследуемого материала, заключающиес в измерении параметра материала при положительной и отрицательной температурах, требуют много времени дл проведени анализа, и результаты их завис т от диэлектрических свойств исследуемого материала.The known methods for determining the moisture content of the material under test, which consists in measuring the material parameter at positive and negative temperatures, take a long time to perform the analysis, and their results depend on the dielectric properties of the material under study.
Дл исключени зависимости диэлектрических свойств исследуемого материала и экспрессного проведени анализа по предлагаемому способу измер ют объем материала при положительной, затем при отрицательной температурах и по разности полученных значений объемов определ ют искомый параметр.To eliminate the dependence of the dielectric properties of the material under study and the rapid analysis of the proposed method, the volume of the material is measured at a positive, then at negative temperatures and the desired parameter is determined from the difference in the obtained volume values.
Сущность способа заключаетс в следующем .The essence of the method is as follows.
Определенную пробу исследуемого материала загружают в датчик и измер ют одним из известных способов изменение объема исследуемого вещества при положительной и отрицательной температурах. Изменение объема исследуемого материала может быть осуществлено цутем измерени разности давлени над исследуемым материалом, либо путем измерени разности давлени внутри его. При этом влажность определ ют по формулеA specific sample of the test material is loaded into the sensor and, by one of the known methods, the change in the volume of the test substance at positive and negative temperatures is measured. The change in the volume of the test material can be carried out by measuring the pressure difference over the material being studied, or by measuring the pressure difference inside it. The moisture is determined by the formula
.ДР,.Dr
где W - влажность, k - коэффициент, завис щий от конструкции датчика, ДЯ -разность давлени при положительной и отрицательной температурах.where W is the humidity, k is the coefficient depending on the sensor design, RL is the difference of pressure at positive and negative temperatures.
Предмет изобретени Subject invention
Способ определени влажности исследуемого материала путем измерени параметра материала при положительной и отрицательной температурах, отличающийс тем, что, с целью исключени зависимости диэлектрических свойств исследуемого материала и экспрессного проведени анализа, измер ют объем материала при положительной, затем при отрицательной температуре и по разности полученных значений объемов определ ют искомый параметр.The method of determining the humidity of the material under investigation by measuring the material parameter at positive and negative temperatures, characterized in that, in order to eliminate the dependence of the dielectric properties of the material under investigation and express analysis, the material volume is measured at a positive, then at a negative temperature and difference between the obtained volume values determine the desired parameter.
