Enclosure & Electronics Cooling, Liquid Cooling and Signaling Solutions

The development of Industry 4.0 in machine processes will increase automation and process safety, data exchange through the industrial Internet of Things (IoT), big data and data analytics. 

This new trend brings new challenges for companies as safety now also depends on the proper functioning of electronic components and systems.  Pfannenberg's Signaling Solutions consequently reduce the risk of system failure thanks to documented statistical data, self monitoring, and process fault reporting.

SIL TO MEASURE SAFETY SYSTEMS PEFORMANCE

SIL or Safety Integrity Level is the target statistical representation of the reliability of a Safety Instrumented System (SIS). In order to achieve the target SIL rating, all components of the SIS must realize the target SIL. There are four integrity levels associated with SIL. The higher the SIL level, the lower the probability of failure on demand for the safety system and the better the system performance.

To support the safety goals of machinery and processes that strive to comply with SIL, all risks must be adequately mitigated. Even after all possible design criteria and complementary safety barriers are considered, a risk gap may still remain for many circumstances. In such situations, a signaling solution will help narrow the risk gap.

Systems that require SIL signaling are generally divided into two application categories: machinery alarms and process alarms.

PFANNENBERG SIL COMPLIANT SIGNALING SOLUTIONS 

For many years Pfannenberg has provided SIL 1 and SIL 2 compliant signaling technology for harsh industrial environments. Equipped with the key safety data, the sounders and flashing lights can be integrated in the safety concept of machines and plants without any problems.
