An important parameter in many areas of process control is the measurement of concentration, dry substance or water content for optimization and control, as well as for improving quality. Interfering factors such as color, in homogeneity, deposits etc. should have none or only a negligible effect on the measuring value.

System configuration

Micro-Polar consists of the evaluation unit, the microwave sensor and a high frequency quad cable. The microwave sensor can consist of:

• measuring cell of various nominal widths
• container probe
• container probe with flushing device.

An important parameter for the extraction of sugar is the concentration of the sugar massecuite. Measurement of the dry substance content, usually represented as Brix is absolutely essential in order to optimize, control and improve the sugar quality. Based on experience in process control, BERTHOLD TECHNOLOGIES provides products, which exactly match the instrument needs and expectations of customers producing sugar.

Principle of measurement

Microwaves penetrate the product to be measured, causing free water molecules to rotate, resulting in phase shift and an attenuation of the transmitted microwaves. Micro Polar Brix uses two parameters to determine the concentration while compensating for influences of different products and for variations in the purity of the sugar concentrate.

System configuration

Micro Polar Brix consists of the evaluation unit, the microwave sensor and a high frequency quad cable. The microwave sensor is available in two versions, as a batch pan probe without flushing device and as a continuous pan probe with flushing device.

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.

The measuring system LB 444 is used for contactless, continuous measurement of liquids or bulk materials in pipes and vessels. It can easily be installed on existing pipelines without downtime. It works reliably and is unaffected by color, temperature, pressure, or chemical properties of the product to be measured.

Applications:

• Concentration measurement of acids, alkalis, saline solutions and suspensions
• Crystallization and polymerization monitoring
• Measurement of the solid matter content in slurry, in flue gas desulphurization suspensions, in aluminum production and in mining.
• Determination of the bulk density in washing powder and clinker.

The measuring system LB440 is used for the contactless, continuous measurement of liquids and bulk materials in reactors, vessels and bunkers. The measurement is not affected by the chemical and physical properties of the product being measured. The level measurement is adapted to the specific geometry of the vessel.
