Explanation/Annotation:For operational production control of moisture content of timber according to the state standard 16588 and wide assortment of construction materials, including in articles, designs and structures according to the state standard 21718.
Detailed model description:The device make it possible of humidity control of granular and fibrous materials (the grit, the backfillings, the grounds, the warmer), solid materials (the concrete, the solution coupling, the plaster, the brick) and the woods in laboratory, industrial and full-scale conditions. The principle of operation of the devices is based on correlative dependence of electric inductivity of material from content in they moisture in case of positive temperatures. Exists three measurement regime: single measurement, measurements series with averaging and condition of continuous measurement for interval selection increased moisture content. The non-volatile memory noticeably makes easy the process of data storage and creation of account reports.
the technical characteristics:
1. Range of humidity measurement:
wood: - pine, birch, larch, Dubov, beech, aspen, spruce: 4. 60
construction materials:
- concrete heavy 1. 5; - concrete fine-grain (cement and sand grout slurry): 2. 15; - concrete on artificial porous fillers by the density 1000. 1800 êã/ì3 2. 20; - concrete cellular (gas-, foam-beton) density 400. 1000êã/ì3: 2. 45; - brick ceramic (continuous): 2. 15; - brick silicate: 2. 10
granular materials:
- grit we river, fineness modulus of Ì1, 8 and Ì2 8: 1. 15; - fractions crushed stone 3. 10: 1. 5; - crushed stone of fraction 5. 20: 1. 3; - ãðàíøëàê 1. 15; - slag pumice: 1. 15; - thermoelectric power station ash: 1. 15; - noise like signal (repelling of quarry dust): 1. 152.
3. Main absolute error of humidity measurement, %
- within a range of 1. 10% not more 0, 8%;
- within a range of 10. 20% not more 1%;
- within a range of 20. 30% not more 1, 5%;
- within a range of 30. 45% not more 2%;
- higher 45% do not is standardized.
