Brix and Concentration measurement LB 565

Microwave Analyzer for Brix and Dry Substance

MicroPolar Brix is specifically designed for the sugar industry. It provides online measurement of

  • Dry substance
  • Brix value
  • Density
  • Concentration

The real-time measuring results are essential in order to optimize and control the sugar quality and moreover to ensure an efficient production process. In more than thousand applications worldwide, the Microwave analyzer MicroPolar Brix has proven to work absolutely reliable and accurate.

MicroPolar Brix is available with different sensor types for the installation on vessels (e.g. crystallizer) or pipelines. The high-dynamic version Microwave Transmitter MicroPolar Brix++ provides an excellent measuring accuracy, even for large pipeline diameters.
 

Typical measurements in the sugar beet and sugar cane industry:

  • Brix value during crystallization (continuous or batch-type vacuum pan)
  • Concentration of milk of lime
  • Dry substance of thin and thick juice

New Container Probes for Microwave Moisture Measurement

The new, removable plastic caps made of PEEK with internal thread can be exchanged on site if necessary. The newly developed antenna technology inside ensures higher measurement accuracy and offers more dynamics.

New FlowCell with EHEDG certification

The new FlowCell consists of a stainless steel inline housing and two microwave antennas which are connected via clamp connections and are interchangeable at any time. Due to the certification of the EHEDG it is also suitable for hygienic applications.

Features

Multi-frequency Technology

The measurement is performed with a number of different frequencies per measurement cycle, leading to a very stable and reliable measurement, unaffected by reflexes or resonances.

High Dynamics

The high dynamic range of Microwave analyzer Micro-Polar allows the precise measurement on even very large pipeline diameters.

Reference Line

An integrated reference line makes the measurement independent from potential environmental influences.

Automatic on-site Calibration

The calibration is done directly on the evaluation unit. The software contains a sample taking feature, where laboratory values can be easily entered. The calibration curve is calculated automatically.
