Introduction:

The RHOSONICS Series 9200 is only designed for the Beverage industry for the main processes. Thanks to the innovative electronics and sensor design, continuous in-line monitoring of fluid mixtures is now possible with an extreme accuracy, virtually no maintenance and without moving or degrading parts.

The heart of the system is the cell, in which ultrasonic waves are being generated and received. This cell can be an externally mounted cell,  in a bypass, but may as well be a measuring section, where the liquid is analysed while flowing through the pipe. Several probe designs facilitate the measurement of concentrations inside tanks and processes of beer brewing.

Our analysers offer the following benefits:

Rhosonics introduced the new Brix and Density Analyzer Model 9200 in July 2006, the ultimate system for fully automated inline analysis of beverages. It offers the following distinct advantages, not found on any other Brix or Density Analyzers available on the market.

1. Beverage type specific calibration, based on a new, advanced calibration algorithm;
2. Batch calibrations are stored in memory, saving important labor costs;
3. Automatic calibration for drift, using advanced continuous correction method;
4. Automatic self test routine;
5. Graphic Touch Screen Display;
6. Trend Analysis;
7. PLC control for switching of calibrations

1. Beverage type specific calibrations.
With the Model 9200 Brix and Density Analyzer, it is no longer necessary to calibrate the analyzer for specific beverage types.
The Rhosonics Brix and Density analyser can store 255 different beverage types. As beverage specific data is stored per beverage type, tedious and time consuming calibrations for each product change are no longer necessary. 

2. Batch calibrations are stored in memory
When you detect small deviations with the laboratory results of a field grabbed sample, the Model 9200 allows you to easily correct its calibration. In addition, this information is stored as well in the built-in beverage specific database, making this calibration only necessary once for each beverage type.

3. Automatic system calibration
Other equipment vendors require frequent recalibration of the system, some even every day. The ultrasonic sensor of the Model 9200 is automatically monitored during the inline analysis, while a unique and proprietary method eliminates system drift. This calibration, which is normally done in the factory as part of the final calibration procedure, is now performed automatically and continuously, without operator actions. The results are considerable savings on maintenance costs, and increased accuracy of the inline analysis.
Another calibration which can be performed automatically, is the zero calibration (water calibration). Previously, this calibration had to be performed by an operator, while water was running through the pipe. With Model 9200, the system can be remotely given a command to perform the calibration. When the remote liquid selection option is used, liquid number zero forces the analyzer to calibrate itself, adjusting the necessary parameters fully automatically. This feature provides additional savings on maintenance costs, and because the analyzer carefully checks all parameters that can affect this calibration, the zero point calibration is realized with the same accuracy as a well performed manual calibration in the laboratory.

4. Automatic self test routines
Of course the Model 9200 Brix and Density analyzer checks the integrity of its components, as well as unusual occurrences in the process.

5. Graphic Touch Screen Display
Thanks to a water and shock proof Touch Screen, the control of the analyzer is greatly simplified. In contrast with other systems, the small arrow buttons and complex menu navigation is replaced by easy to recognize, context dependant icons, pop-up screens with additional information and pop-up key-pads for direct entry of numbers and letters. A manual is rarely needed and the time to learn the system and its menu structure is shortened greatly.

6. Trend analysis
Besides a user configurable display, this model offers you the possibility of displaying concentration and temperature trends, providing additional on-the-spot information.

7. PLC control
Model 9200 can be fully integrated in automated beverage production environments.
The stored calibration can be activated, using a binary code, which can normally be generated by PLC systems, or through the built-in RS-232 serial communication port.
