The cortoller (A) is the central evaluation unit for between one to four measuring points. Ln the display you can see measurement values such us concentration, density or other concentration units with the related process temperature. All measurement values are digitally available through the RS 232 interface. The main
measurement value for the concentration is transferred to the process control system by the classical 0/4 _ 20 mA current interface. You can adapt the system parameters and the calibration data to your specific measuring task by using the well_ structured multilingual menu of the controller.
The complete microwave electronics are mounted in the extraordinarily compact microwave module (B) which is installed close to the sensor (C).

The controller lCC 2.45 has 4 isolated outputs 0/4 _ 20 mA. For the realisation of more than one measurement up to 4 microwave modules can be connected. Each module has its own settings and calibration to measure independently from the other modules. The calibration and setting of each measurement can be effected without interference from the measuring channels which are already used for process control. Each measurement and its settings can be shown separately on a big display or you can choose all 4 measuring values in the display together.
Even if you only operate one measurement: the remaining measuring channels can be used for different ranges or different calibrations (product specific multiple calibrations).
