The characteristic measurement equipment of one or more of rose condition material and fractionation body extracting equipment inspection manner and device null from rose condition

摘要

PURPOSE: To improve the accuracy and reliability of the characteristic measurement of a bulkyl substance by measuring external variables affecting the normal operation of a measuring apparatus in parallel irrespective of characteristics to be measured, and totally obtaining the measured value. CONSTITUTION: One or more characteristics of a bulky substance such as, for example, moisture content of coal are monitored, measured by sensors 17 to 21, and predetermined data are recorded in a mechanical sampling unit 14. Simultaneously, one or more coefficients for affecting the accuracy and reliability of the result obtained by an apparatus for measuring the one or more characteristics of the substance by the direct or indirect influence of normal operation of the apparatus irrespective of the apparatus for measuring the characteristics of the substance such as, for example, the influence of magnetism to the apparatus for measuring a magnetic coefficient by providing a magnetic separator in a coal treating apparatus is excluded. Eventually, these data are totally integrated to obtain a measured value.
