Global safety certification provider, exida, certified the product reliability and the design and engineering processes for the Rosemount 3051S pressure transmitter with advanced HART diagnostics as Safety Integrity Level (SIL) 3 capable per IEC 61508.
“Emerson Process Management has demonstrated that its product design and development processes for the Rosemount 3051S pressure transmitter with advanced diagnostics meets the requirements of the IEC 61508 safety standard,” said exida Principal Partner Dr. William Goble. “The end result of having equipment with a low failure rate and high diagnostic coverage is not just improved safety, but also lower downtime.”
exida performed a Failure Mode Effect and Diagnostic Analysis (FMEDA), a structured, quantitative analysis which predicts failure rates, modes, and diagnostic coverage and their effects on system operation. The FMEDA results provide SIS designers with the detailed reliability data required for SIL Verification compliant with IEC 61511.
“Combining a high safe failure fraction (> 96%) with broad diagnostic coverage and the ability to detect process / installation issues such as plugged impulse lines increases proof test intervals and reduces total cost of ownership,” said Bill Zhou Rosemount Product Marketing.
