Density measurement with SENSseries LB 480


Highly sensitive detectors for contactless density measurement

The SENSseries LB 480 density meter is a compact field device that combines top of the class measuring technology with maximum manufacturing quality and innovative features - the best system for challenging measuring tasks:

  •           Density measurement
  •           Concentration measurement
  •           Solid content measurement

Functional safety

The high reliability of the measurement is supported by important diagnostic functions, such as permanent monitoring of the detector function by crosschecking the cosmic background radiation and much more. This guarantees outstanding operational safety.
The cosmic radiation control also makes it possible to keep the required source activity very low. Only Berthold Technologies is able to use the LB 480 as a density or min/max level switch in SIL2 / 3 safety circuits, in addition to its use as a level field device.

Perfect for the highest demands - our benefits at a glance


• Compact field probe with integrated evaluation unit
SIL 2 or SIL 3 with homogeneous redundancy
• Process connection via HART
• Quick-Start menu for effective, fast and easy to use start-up
• Continuous self-monitoring through the unique and unrivalled
   cosmic radiation control by Berthold
• Patented 4 ... 20 mA current output
• High immunity to interference (SIL standard)

Be SENSitive

Berthold density measurement SENSseries detectors offer optimum sensitivity and extremely high measurement accuracy. This makes it possible to work with very low source activities - a big advantage in terms of shield costs and radiation protection measures.

Density measurement with SpeedStar

The product version SpeedStar is used when very fast process changes have to be recognized immediately. SpeedStar offers a uniquely short cycle time of 50ms. One application is the thickness measurement of plates or pipes that are conveyed during manufacturing.
