Offline/laboratory sampling |
| Samples processed per hour |
10.000 - 40.000
An online system processes more samples in 5 minutes than a laboratory in a week. |
5 - 20 |
| Time taken to correct the process |
None. The process is corrected immediately and continually. |
min. 5-10 min. The process is corrected once to reflect the situation 5-10 min earlier. The process is only corrected again after the following sample is processed. Again with significant delay. |
| Ability to monitor cross profile uniformity |
Yes. The cross profile of the product is monitored continuously. |
No. |
| Automatic control of key parameters |
Easy to implement. |
Not possible. |
| Ability to detect systematic patterns of faults (resulting from problems in the production line) |
Yes. |
No. |
| Roller wear monitoring |
Yes. |
No. |
| Time needed to change paper grade |
Immediate detection of in-spec quality -> less waste, less time. |
Waste because of slow sample processing. |
| Measurement data collection |
Automatic. |
Manual. |
Measurement data processing and analysis.
Ability to link automatically to process management systems (MIS). |
All links exist. Easy to integrate and tailor to specific requirement and needs. |
Manual. |
| Ability to implement Quality Standards on the production line |
Very easy. All required data exists and can be processed automatically. |
Manual and cumbersome. |
| Savings created through process optimization and reduction of waste. |
Significant. |
Process is not optimized and therefore no benefits are materialized. |
