Core Product Series XIR Series Online Near Infrared Moisture Measurement System Water exhibits strong absorption characteristics for some infrared light of specific wavelengths. When the material is irradiated with infrared light of these specific wavelengths, the water contained in the material will absorb part of the energy of the infrared light, and the more water content is absorbed. Therefore, the moisture content of the material can be calculated by measuring the intensity attenuation of the reflected light. Since the reflectivity of materials to infrared rays varies due to their different absorption characteristics and stray characteristics, if only the absorption wavelength of water is used, the surface state, color, structure and other factors of the material will interfere with the measurement of moisture content; for this reason, the three-wavelength method is adopted, namely, a wavelength that is easily absorbed by water (measurement wavelength) and two wavelengths that are not easily absorbed by water (reference wavelength), detecting and calculating the ratio of the energy of the reflected light at these three wavelengths can eliminate the interference of other factors on the measurement of moisture content. Illustration: Mainly composed of a microwave transmitter and at least one receiver Performance characteristics The near infrared analyzer has the advantage of high performance and low cost. The dual-beam optical system has high measurement stability and avoids any systematic errors. The system is not affected by factors such as temperature, grain size, test distance, high speed and moving products with large measurement areas.

Applicable industry Tobacco: tobacco leaf, cut tobacco, stem, thin sheet, pence, filled cigar, tobacco grinding, etc. Chemicals: PVB film, PVC powder, rubber chips and additives, acetate, soda, detergent, fertilizer, laminated glass, medicine, sodium benzoate, etc. Food: Corn starch, sugar, coffee, chocolate, tea, potato starch/puree/piece, feed, milk/cocoa powder, biscuits, pulp, alfalfa Woodworking and papermaking: wood, sawdust, cardboard, fiberboard, paper, corrugated board, printing paper Minerals: sinter mixture, carbon powder, coke powder, peat, copper ore, nickel ore, bauxite, ore, bentonite Building materials: soil, brick, gypsum board, gypsum powder, ceramic raw materials, ceramic tiles, cement, sand Other: textile industry, glass fiber production, glue production MOCON Series Online Microwave Moisture Measurement System One characteristic of microwaves is that they can propagate through non-conductive materials. In ambipolar molecular structure materials, such as water, the electric field of microwaves can cause oscillations during propagation through the medium. In the process, the microwaves lose some energy. This energy loss increases with the increase of the water content of the medium. The results show that with the increase of the water concentration, the less microwave energy will be transmitted to the other end of the medium. Water not only absorbs, but also reflects some microwave energy. By using these two effects (absorption and reflection), the measurement of moisture in the medium can be achieved with microwave technology. The system is generally composed of four parts: measuring probe, microcomputer processor, special cable and debugging and diagnosis software. Performance characteristics Microwave is not sensitive to the pH value and conductivity of the measured medium. The total moisture content (both superficial and intrinsic) can be measured. Non-contact measurement: the sensor has no wear, does not stick to the material and does not interfere with the production process. The measurement can give instantaneous results (real-time measurement) and can be used for on-line measurement of process technology. The accuracy of the measurement mainly depends on the particle distribution characteristics of the medium. Generally speaking, the coal particle size is 0 - 20mm and the measurement error is 0.5. The accuracy of materials with uniform particle size distribution will also be improved accordingly, for example, the measurement error of sand is ± 0.1%, and the measurement error of copper ore is ± 0.3%. Applicable industry Iron and steel: incoming raw materials, stockyard stacking materials, batching room (mixed ore, coke powder, coal powder, quicklime, etc.), sintering mixture, blast furnace coke, pellets Electricity: incoming raw materials, stockyard stacking materials, coal conveying system, coal grinding system, boiler pulverized coal, slag, ash and limestone Coal: lump coal, peat, pulverized coal, coal, coke, hot coal, coking coal, trade settlement Coking: incoming coal raw material, stock yard, coal conveying system, coal grinding system, drying system, coke oven pulverized coal, coke Non-ferrous metals: bauxite, copper concentrate, mineral sand, nickel ore, gold, silver, lead and zinc concentrate, alumina and non-ferrous smelting Building materials: sand/gravel quartz powder, sand, brick (raw material), ceramic (raw material), mortar Tobacco: cigarette packs, tobacco stems, tobacco leaves, tobacco shreds, re-roasting, tobacco branches Recycling: waste paper, wood chips, bamboo chips, biomass, sludge, compost Application Case STEEL Steel Industry The demand for coke in the iron and steel industry is mainly concentrated in the subdivision processes such as sintering, blast furnace and ferroalloy production. The amount of coke water content in the coke bunker under the metallurgical blast furnace trough is directly related to the accuracy of the coke ratio, and whether the coke water content measurement is accurate or not directly affects the composition of the blast furnace ingredients, thus affecting the blast furnace production. COAL Coal Industry The moisture in coal changes regularly with the deepening of the degree of coal metamorphism: from peat → lignite → bituminous coal → low-rank anthracite, the moisture gradually decreases, while from low-rank anthracite → old anthracite, the moisture increases again, thus, the degree of coal metamorphism can be roughly inferred by the moisture content. The moisture of coal has a great influence on its processing and utilization, trade and storage and transportation. TOBACCO tobacco industry In the production process, the water content of tobacco not only affects its physical properties such as elasticity, toughness, filling and combustion, but also endangers its appearance and internal quality such as color, luster, aroma and taste. At the same time, it also endangers the weak biochemical changes in tobacco, such as the activities of various enzymes, the reproduction of molds, the decomposition and transformation of the substances contained therein, and so on. In each production and processing link, there are strict control and requirements for tobacco moisture. POWER Electric Power Industry The power industry is the most important basic energy industry in the development of the national economy. It is a power production and consumption system composed of power generation, transmission, substation, distribution and electricity consumption. Moisture measurement is widely used in all aspects of the power industry (e. g. Example 1: Fuel coal is the most important cost of thermal power plants. Under normal circumstances, the power generation process of power plants consumes huge coal resources. Total moisture measurement data is the basis for coal pricing and benchmark conversion, and this index directly affects the results of coal pricing. Example 2: The main factors affecting the insulation strength of transformer oil are moisture in transformer oil, particulate impurities, trace bubbles and temperature in oil, etc., which need to be measured online in real time to ensure the normal operation of instruments). CHEMICAL chemical industry In the field of chemical industry, there are many kinds of chemical raw materials, such as chemical liquid, chemical fertilizer, chemical oil, chemical powder and so on. Chemical raw materials require real-time online detection of the moisture content of raw materials during the production process (for example, in some liquid chemical products and intermediates, the moisture content is one of the important indicators of product quality. Excessive moisture will destroy the chemical reaction, produce by-products, and reduce the yield.), Ensure the safety and quality of chemical products and production. ※ Note: Due to similar uses in different industries, the picture scene is for reference only, and the actual application configuration shall prevail.

1. Selection of sensitivity The sensor of the servo electric cylinder is very important. The higher the sensitivity, the more accurate the measurement result, but the higher the sensitivity, the more susceptible to interference from external factors, which can easily lead to measurement accuracy. Therefore, it is necessary to reduce the working area when in use. Devices that may interfere with the signal.

Servo system is an automatic control system, it makes the object position, direction and state of the output controlled quantity follow the input target (or given value) of any change. Servo mainly by pulse positioning. Basically, it can be understood that when the servo motor receives the pulse, it will rotate an angle corresponding to the pulse to achieve displacement. Since the servo motor itself has the function of sending pulses, the servo motor will send a corresponding number of pulses every time it rotates an angle, which corresponds to the pulses received by the servo motor, or is called a closed loop. In this way, the system will know how many pulses are sent to the servo motor and how many pulses are received at the same time.
