Can the Rosemount 3051 or Rosemount 3144P be SIL approved by TV, FM, or exida.com for SIS applications?
No — a single measurement device cannot be approved or certified per a SIL level. The reason is that the SIL level 1-4 applies to the entire SIS loop (Transmitter + Logic Solvers + Valves + power supply + other loop equipment.) as defined in ISA S84.01 and IEC 61508. The end user must define the level of SIS required for the application and determine the level of documentation required. What we can say is the Rosemount 3051 and the Rosemount 3144P transmitters are suitable for use in SIS applications due to our quality control, quality design, and history of high reliability in actual field conditions, MTBF data, and the TV or exida.com review.
