Density Transmitter DuoSeries LB 474

DuoSeries LB 474 is the new radiometric density system from Berthold based on real 2 wire technology, succeeding and compatibleour top-selling density measurement system LB 444. Like its predecessor model, the measuring system DuoSeries stands out by a particularly excellent performance with high accuracy and repeatability of density. 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 density measuring system consists of a scintillation detector – CrystalSENS point detector – and a sophisticated transmitter unit for display and operation. The density transmitter is a state-of-the-art control unit with robust 3.5” TFT touch panel, powerful Dual Core CPU, up to 4 calibration curves, compensation of product temperature variations via PT100 connected to detector or analog current input and diverse operator interfaces. The calibration parameters can be exported via the USB port and can be easily imported to devices at other measuring tags. 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.
