Level Transmitter DuoSeries LB 470

DuoSeries LB 470 is the radiometric level system from Berthold based on real 2 wire technology succeeding our top-selling level transmitter LB 440. Like its predecessor model, the measuring system DuoSeries stands out by a particularly excellent performance with high accuracy and repeatability of level. Due to its outstanding performance the DuoSeries is the preferred choice when processes are demanding and 2-wire based control room technology is required.

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.
