Pentair achieves SIL 3 certification for Westlock position monitors and control monitors

Pentair has received a Safety Integrated Level (SIL) 3 certification for its Westlock Controls AccuTrak position monitors and Quantum control monitors.

Obtained from third party certification organisation Exida, the accreditation validates the monitors’ quality and reliability in hazardous application environments.

Mike Lutolf, global product manager for controls at Pentair, comments: “Typically, many products on the market are SIL 3 capable, but not officially certified. By offering products that meet Exida’s stringent design and quality requirements, we are going beyond the industry norm to ensure full compliance with SIL 3 applications.

After passing rigorous Failure Modes, Effects, and Diagnostic Analysis (FMEDA), Pentair’s successful assessment confirms that products across its entire AccuTrack and Quantum lines are capable for use in SIL 3 applications in low demand mode, where systems operate less than once a year.

Depending on the application, SIL 3 certified products also reduce the risk of accident by a factor of 10 compared to SIL 2 devices.
