Simple and straightforward in operation
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 the safe function of the system. Furthermore the data logging functionality allows operators to analyse their processes in depth, e.g. develop trends, track process changes etc.
Radiation Interference Discrimination (RID)
DuoSeries LB 470 is now also available with radiation interference detection (RID). The level measurement system with RID consists of a Co-60 measuring source and the UniSENS rod detector or the highly sensitive SuperSENS detector along with a separate transmitter for display and operation. The detector mounted at the measuring point is connected to the transmitter LB 470RID via a two-wire cable. If you want to continue measuring despite impending external radiation, then the LB 470 RID version is the right choice.
Gas Property Compensation (GPC)
In the case of radiometric measurement, gas density variations can falsify the measured value, unless you have a gas density compensation from Berthold. 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 realised, which provides an unaltered measured value even with fluctuations in the gas density.
Whitepaper “Radiation Interference Discrimination (RID)”
Berthold has published the whitepaper “Radiation Interference Discrimination (RID) – Managing Interference Radiation in Radiometric Level Measurements”, wherein the common sources of interference radiation are identified and effects on the nucleonic measurements are explained. The paper elaborates on how Berthold, with its highly sophisticated radiation interference detection (RID) feature, helps plant operators to maintain a reliable and repeatable measurement.
