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.

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.

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.
