DuoSeries LB 470 is the radiometric level measurement from Berthold in true 2-wire technology, which is now also available with radiation interference detection (RID). The level measurement DuoSeries is characterized by a particularly high accuracy and reproducibility. The level measurement system DuoSeries consists of a Scintillation detector - CrystalSENS point detector or UniSENS rod detector - as well as a separate transmitter for display and operation. The modern evaluation unit has a 3.5" touch panel, a powerful dual core CPU and various operating options. In addition, advanced functions for self-diagnostics and monitoring ensure the highest functional safety of level measurement during operation. In addition, operators can use the data log functions for detailed process analysis, such as tracking trends and process changes.
RID (Radiation Interference Discrimination)
If you want to continue to measure with impending external radiation, then the "LB470RID" version is required. The measurement continues without interruption, even if external radiation is present. External radiation is detected due to its different energy. The detector then changes to a second measuring channel and continues the measurement without error. This patented process makes the system particularly reliable. RID has been field tested for many years. In the new LB 470 series, operation has been made significantly more user-friendly for RID, making system calibration much easier.
Does the gas pressure in your vessel change?
In the case of radiometric measurement, this can falsify the measured value, unless you have a gas density compensation from Berthold Technologies. With the feature GPC (Gas Property Compensation), a second measurement determines the current gas density in the tank and has a compensating effect on the connected level measurement. Thus, a level measurement is realized, which provides an unaltered measured value even with fluctuations in the gas density
