Mobrey Horizontal Magnetic Float Level Switches Approved for Safety Instrumented Systems Up to SIL 2

I wanted to pass along this news, Emerson’s Mobrey Horizontal Magnetic Float Level Switches are approved for safety instrumented systems. The release opens:

 Emerson Process Management announces that selected models of its Mobrey Horizontal Magnetic Float Level Switches have been certified in accordance with IEC61508 to attain (Safety Integrity Level) SIL 1 for a single device and SIL 2 for a pair of devices.

Following successful third-party evaluation by global organization Exida, Mobrey Horizontal Magnetic Float Level Switches have the required Failure Modes, Effects and Diagnostic Analysis (FMEDA) report. The models assessed and certified are typically used in the oil and gas, power, refining and chemical industries, and are ideal for high and low liquid level alarm, overfill alarm, and pump control duties.

The use of certified devices provides a measure of quality and reliability, making it much easier to design and implement a safety system in process applications that must comply with the IEC 61508/61511 functional safety standard.
