Ash analyzer is specially designed to work in difficult conditions such as those in coal mining and processing it. Analyzer allows a precise determination of ash content and calorific value of coal, even on conveyors belts, in a continuous manner, without being affected by heat or dust in the process of measuring. Radiation emitted by a gamma source is attenuated by the passage on the coal conveyors belt.

Last generation of scintillation detectors with mounted opposite sources recorded radiation intensity transmitted. As the ash content of coal has a higher absorption than the fuel, the absorption is a direct measurement of ash content in coal on the conveyors belt.

The LB 442 system is used in the precise mass flow determination of solid matter in a variety of conveyor systems. With many conveyor systems, the radiometric weighing system is the only suitable method for determining mass flow. The Berthold system can also be used to determine the mass flow in “free fall” in pipes or chutes.

The LB 442 provides both the flow rate as well as totaling the mass of solid matter over an individually selectable measuring range from 0-200 kg/h up to 0-10 000 t/h. With the LB 442, measurements can be taken directly after bunker, chute out-lets or transfer systems. From fine powders to large particles weighing more than 10 kg, the LB 442 measuring system is used worldwide.

Umiditatea unui material poate fi evaluata prin efectul apei asupra unui fascicul de microunde.

Moleculele de apa determina o atenuare si un defazaj.

Metoda este aplicabila pentru determinarea umiditatii unor materiale neconductoare sau cu conductivitate redusa, de ex: bauxita, bentonita ingrasaminte, gips, hartie, sare, cereale, nisip, zahar, cherestea, fibre minerale, carbune, etc.

Domenii de interes: industria extractiva, industria alimentara, materialele de constructii.

Se poate determina umiditatea unui flux de material care incarca o banda transportoare sau trece printr-un jghiab cu pereti nemetalici.

Echipamentul include:

• Perechea de antene emisie-receptie microunde
• Unitatea de evaluare Micro-Moist LB 456

Un sistem radiometric, cu sursa de radiatie gamma si detector de scintilatie, poate furniza o informatie asupra masei materialului pe unitatea de suprafata. Acest semnal poate introduce o corectie in unitatea de evaluare Micro-Moist LB 456.

LB 471 is used in all branches of industry, including the food. This system of measurement where applicable should be monitored one or more levels of alarm level of liquids or solid materials. LB 471 can be installed on all types of pressure vessels or tanks such as storage vessels with agitator, high pressure reactors, etc.

The Moisture Meter LB 350 has been designed to measure the moisture content of a variety of different products.

For example:

• in bunkers
• on weighing tanks
• on feeding tanks

The large measuring volume of up to 1 meter in diameter assures a representative measured value.
