By optimizing the activity distribution in the rod sources for the mould level measurement, we significantly increase the accuracy in the upper part of the measuring range. This minimizes the statistical noise without increasing the overall activity of the source.
If you are content with your current accuracy, AOS can be used to reduce the source activity while maintaining the same accuracy. Depending on the application, this may allow for the use of a smaller shield. In many cases, the more cost-efficient lead shield may be used instead of tungsten.
Co-60 rod sources are used as a standard in mold level measurements. The special feature: the activity is customized and continually distributed across the rod length, only possible with Berthold's unique manufacturing process. The custom and continual distribution of activity across the measuring range ensures the best measurement accuracy.
Radiometric based mould level measurement is the dominating technology for measuring the steel level in continuous casting. Herein we discuss performance, statistical variation, influencing factors, source selection, and a recent development that enables the simultaneous measurement of casting powder layer thickness.
The unique short cycle time of 5 ms provides the ideal basis for reliable control.
Detector temperature and status are continuously monitored and displayed.
Comprehensive self-diagnostics and plausibility checks of measurement and calibration ensure the highest process reliability.
By using several calibration points, non-linearities of the calibration curve are eliminated completely, and high accuracy can be achieved over the entire measuring range.
The large colour touchscreen makes operation and calibration particularly easy. The ability to select from different operating languages facilitates ease of operation, regardless of where the system is installed.
Benefit from faster response times during start-up of casting, by setting a smaller time constant in the low measuring range.
Up to four strands can be measured simultaneously. Each measurement channel is equipped with its own power supply and CPU. Therefore, the channels are independent of each other and high process reliability is guaranteed.
Continuous monitoring of the current output ensures highest reliability and signal stability with a patented plausibility test.
