Description
(54) СПОСОБ ГРАДУИРОВКИ ВЛАГОМЕРОВ СЫПУЧИХ МАТЕРИАЛОВ(54) METHOD FOR CALIBRATING MOISTURE MATERIALS
1one
Изобретение относитс к приборам дл определени влажности.The invention relates to instruments for determining humidity.
Известные способы дл градуировки емкостных влагомеров сложны в эксплуатации.Known methods for calibration of capacitive moisture meters are difficult to operate.
По предлагаемому способу с целью унрощени эксплуатации и получени универсальной шкалы прибора градуируют влагомер с навеской материала одного сорта, затем дл каждого из последующих сортов материала подбирают навески таким образом, чтобы емкость датчика с этой навеской соответствовала емкости первоначального материала при той же влажности.According to the proposed method, in order to simplify the operation and obtain a universal scale of the device, a moisture meter is calibrated with a sample of one grade, then for each of the following grades of material, we select hinges so that the sensor capacity with this weight matches the capacity of the original material at the same humidity.
Сущность способа заключаетс в том, что выбираетс навеска дл сорта сыпучего материала , имеющего наименьшее приращение (например, 100 гр. дл муки высшего сорта). Градуируетс прибор с помощью метода сушки , строитс градуировочна крива на весь диапазон влажности. После этого градуировочные кривые отдельных сортов подгон ютс к полученной кривой путем постепенного изменени величины навески пробы данного сорта материала. В результате дл разных сортов материала получаетс одна градуировочна крива с указанием веса навески дл различных сортов муки.The essence of the method lies in the fact that a weight is selected for a variety of bulk material having the smallest increment (for example, 100 grams for high-grade flour). The instrument is calibrated using the drying method, a calibration curve is constructed for the entire range of humidity. After that, the calibration curves of individual varieties are adjusted to the obtained curve by gradually changing the sample size of the given grade of material. As a result, for different grades of material, one calibration curve is obtained indicating the weight of the sample for different grades of flour.
