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 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.

Features

  • 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
  • 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

Sources & Shields

Radiometric measurement systems require a radioactive source, emitting gamma radiation. The radioactive material is safely sealed in an absolutely tight and durable capsule, which guarantees safe handling - even under extreme measurement conditions. 

Our shields - made from steel or stainless steel  - filled with lead or tungsten or both - offer the best shielding effect in every possible situation. The shield or rather the lock or seal remains closed until the measurement is put into operation.
