High reliability is supported by important diagnostic functions, such as permanent monitoring of the detector functionality by crosschecking the cosmic background radiation, and much more. This guarantees outstanding operational safety. Cosmic radiation control also makes it possible to keep the required source activity very low.
Berthold's LB 480 SIL model is unique in the radiometric gauge market for being certified for density and low level switch measurements, in addition to high level switch and continuous level measurements.
control allows our detectors to work with very low source activity. This minimizes shield costs and reduces required radiation protection measures.
Due to this high stability and sensitivity, it may be possible to postpone source replacements for years with the use of our standard detectors and especially with our most sensitive SuperSENS detectors.
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, measuring a density profile on pipes or plates detected directly during extrusion, detecting plugs traveling down pipelines, and the liquid level inside bottles while the bottles are still being transported.
With this function, weld tests no longer cause sudden fluctuations in the measured value. When weld tests are detected, the measured value is frozen until the external radiation event ends. A digital output signals the detection of interfering radiation. All of our level measurement detectors are equipped with XIP.
The SENSseries LB 480 detectors are certified for use in SIL 2 applications. Even SIL 3 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.
