Proven 2-wire technology with trend-setting functions

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. Because of its superior quality, the DuoSeries is the first choice for demanding processes and wherever maintenance and control technology is used.

Measuring principle level measurement

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.

The DuoSeries measuring system consists of a scintillation detector – CrystalSENS point detector or UniSENS rod detector – and a sophisticated transmitter unit for display and operation. The transmitter is a state-of-the-art control unit with robust 3.5” TFT touch panel, powerful Dual Core CPU and diverse operator interfaces. Advanced self diagnostics and monitoring features ensure a safe function of the system. Furthermore the data logging functionality allows operators to analyze their processes in depth, e.g. develop trends, track process changes etc.

RID (Radiation Interference Discrimination)

Level measurement with LB 470 RIDLevel measurement with LB 470 RIDIf 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. More information

Berthold Technologies has published the whitepaper “Managing Interference Radiation in Nucleonic Level Measurements”, wherein the common sources of interference radiation is identified and how affects nucleonic measurements is explained. The paper elaborates on how Berthold with its highly sophisticated RID feature helps plant operators to maintain a reliable and repeatable measurement. It can be downloaded here

Does the gas pressure in your vessel change?

Level measurement on vesselIn 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
