With the microwave measuring systems from Berthold, the juice concentration (°Brix) is monitored throughout the whole crystallization process and a precise determination of the seeding point can be determined. The systems are applied in all crystallization stages. Due to the robust device and the superior sensor flushing, the measuring systems have proven time and time again that they work reliably and trouble-free even in continuous operating conditions.Evenafter the final crystallization stage the °Brix concentration of the massecuite is still measured. In this case the measuring system is positioned at the outlet pipe, after the product has passed through the pump.
Microwaves penetrate the material to be measured. The dielectric constant value of the material determines the materials impact on the microwaves. The dielectric constant value of water is 20 times larger than most other materials. This results in a strong interaction of the microwaves with water, which is then measured as attenuation and phase shift.
Consequently, the water content can be determined very accurately. The multi-frequency technology used by Berthold guarantees very stable and reliable measurements, which remain unaffected by interfering reflections or resonances. The integrated reference line ensures reliable compensation for ambient influences. The MicroPolar works with very low microwave power (approx. 0.1 mW) meaning that the material being measured is not heated or altered in any way.
