SENSseries detectors approved for SIL2 and SIL3 applications

December 2014 Level Measurement & Control

Berthold Technologies’ radiometric gauge SENSseries LB 480 has been awarded SIL2/SIL3 certification. Thus the company is the first supplier providing SIL certified radiometric systems for both level (point level/continuous level) and density measurements. “While the certification for the level gauge was a pretty straightforward task, the density gauges were much trickier to do and only possible due to our years of experience with this technology,” says Thomas Bogner, business unit manager of Berthold Technologies.

The high level of availability and operational safety of the SENSseries LB 480 detectors was intensively tested and approved by TüV Süd according to IEC 61508:2010. In redundancy installations SIL3 can also be achieved.

Moreover, the Berthold detectors offer one of the most stable and reliable measurement performances available on the market. Unlike other instrumentation that requires frequent recalibration, Berthold’s patented stabilisation method corrects for temperature and ageing effects. This provides the customer with a highly reliable system with minimal maintenance – and all in SIL safety.
