Technological Highlights

Simple and intuitive operation

  • Compact field probe with integrated evaluation unit
  • Quick Start menu for easy and quick start up
  • Continuous self-monitoring


State of the art technology

  • SIL 2 or SIL 3 for level, level switch and density
  • External radiation detection - XIP (X-ray interference protection)

Safe for critical processes

The high reliability of the measurement is supported by important diagnostic functions, e.g.  permanent monitoring of the detector function by comparison with 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 is able to use the LB 480, in addition to its use as a min/max level switch as a density or level field device in SIL2/3 safety circuits.


Detector for the most sensitive measuring tasks

The cosmic radiation control allows in many cases to maintain the required source activity very low. Thus, shield costs and the required radiation protection measures can also be kept low.
Do you need to replace the source for an existing and old measurement?
A pending source replacement can, depending on the application, be postponed for many years if the existing point detector is replaced by a SuperSENS.

Fast detection with SpeedStar

The LB 480 SpeedStar can be used where reaction times in the millisecond range are required. While standard measurements calculate a new measured value every 500 ms, the Speedstar version with a measuring time of 50 ms is 10 times faster. This allows very fast object recognition, e.g. detecting the beginning of a steel plate being moved at a relatively high speed on the roll conveyor. The level of gas bottles can also be measured while the bottles are still being transported.

X-ray Interference Protection (XIP)

With this function, weld tests can no longer distort the measured value. The measured value is frozen until the external radiation influence is over. A digital output signals the detection of interfering radiation. All our level measurements are equipped with XIP.

SIL certified option

The SENSseries LB 480 detectors are certified for use in SIL2 applications. Even SIL3 is achieved with homogenous redundancy. The certificate covers all measurement applications, from high level or low level alarms to continuous level measurement and density measurement. Thus safe operation of critical processes is guaranteed.
