 Technical characteristics 2 2 Machine Translated by Google 22 ÿ B 33 230 ÿ a 0 ÿ The importance of measuring the moisture content of raw materials and finished products in industry (chemical, food, construction, building materials, and other mixed industries) is well known, and there is no need for additional information on this issue. 1. A device for determining the moisture content of flexible and fibrous materials and up to 80% at +500 C; atmospheric pressure from 680 to 785 mm Hg; vine ; alternating current energy frequency Familiarize with the method of the extreme. STUDY OF INSTRUMENTS FOR MEASURING THE MOISTURE OF MATERIALS It follows that the physical value of vlagometry is the amount of wet mass in the measuring object, and the term "moisture" should be used in the sense of pure quality [the mass amount of moisture is, for example, 5% in seeds, or the moisture content of sugar is high ( or lower)]. GTMK-12M gas analyzer can have different scales according to O2 . In science and technology, two unitless relative quantities representing the amount of moisture in solid and liquid bodies are widely used: 50ÿ 1 Gs. Analysis Purpose of work: Additional error due to variation in the amount of unmeasured components in the mixture being analyzed Vlagometry is considered a special case of determining the composition of objects: a wet body is considered as a mixture, water and Stand-mounted modification of the gas analyzer 0-21% ob. O2 has a scale. 8 – LABORATORY WORK composed of a dry substance (though it may be a mixture instead of a dry substance). The purpose of measurement is to determine the amount of moisture in a wet body. the mixture being made should have the following parameters when entering the gas analyzer sensor: temperature from +50 to +500 C, humidity up to 90%. Voltage does not exceed does not exceed The total additional error of the gas analyzer consisting of the sum of the normalized values of individual additional errors 2 2. Determining the moisture content of grain samples with a high-speed MOISTURE METER, gaining experience in static processing of the obtained data. Download 2.77 Mb.
