DuoSeries LB 474
Radiometric density system for standard applications
- Unique: radiometric density measurement with intrinsically safe power supply (full Ex-i)
- Easy, intuitive operation via touch screen
- 2-wire technology: only 2 wires in the field
- Advanced self-diagnostics and monitoring features
Overview
The DuoSeries LB 474 is a radiometric density system that offers high accuracy and repeatability for all standard applications, as well as for more challenging measuring tasks. Due to its outstanding performance, the DuoSeries is the preferred choice when 2-wire based control room technology is required.
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 analogue current input, and diverse operator interfaces. The calibration parameters can be exported via the USB port and can be easily imported into other LB 474s. 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.
