Proven 2-wire density measurement technology
DuoSeries LB 474 is the new radiometric density system from Berthold based on real 2-wire technology. The density measuring system DuoSeries determines density with high accuracy and repeatability. Due to its outstanding performance, the DuoSeries is the preferred choice when processes are demanding and 2-wire based control room technology is required.
Technological Highlights
Simple and intuitive operation
• Unique: radiometric density measurement with intrinsically safe power supply (full Ex-i)
• Ideal for all standard applications, but also for tricky measuring tasks
• Easy, intuitive operation via touch screen
State of the art technology
• Important maintenance-oriented diagnostic functions and self-monitoring
• Compatible with the previous model LB 444
• All contemporary Ex-approvals
• Many different dialog languages are available
• Mass flow evaluation
Simple and straightforward operation
The DuoSeries density measuring system consists of a separate scintillation detector and sophisticated transmitter 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 for 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 into other LB474s. Advanced self diagnostics and monitoring features ensure the safe function of the system.
