M Monitoring of the fresh water:
t Demineralization equipment - using conductivity monitoring t Partial demineralization equipment: by monitoring residual hardness (not part of our product range)
The benefits in detail
Better overview of the process
Better overview of the process through centralized process display Actual values indicated as bar chart Trend plot of the measurement values Prioritized display of faults List of maintenance intervals Totalizing of consumption
Increased safety
Designations of the measurement quantities, input/output signals, and logging/alarms can be configured by the plant operator All signals, limits and warning levels can be logically linked (NAND, NOR, RS-FF etc.); the result is available as a switching output/ logging signal
Environmental protection through active monitoring of waste water and exhaust gases
Reduced cost
Better utilization of fuel Integrated control circuits, i.e. separate elec­tronic control units are no longer needed.
Easily integrated and expanded
Modular structure, therefore extendable and suitable for all plant sizes Existing input and output signals are easy to integrate
*) If the high-level alarm does not act on the safety chain, the level switch NRS 1-41 is required.
