Process safety is a top concern for manufacturers with hazardous areas. I received a question on a blog post, Calibrating Coriolis Flowmeters In-Situ: What is Emerson’s statement of proof test coverage (e.g. for SIS testing) for the in-situ tests described in this article? I turned to Emerson’s Tom O’Banion on the Micro Motion Coriolis flow […]
A reader emailed some great questions to an earlier post, Clarifications on the Use of the DVC6000 SIS in Safety Applications. The post, featuring the thoughts of Emerson’s Riyaz Ali, addressed misconceptions about the use of digital valve controllers and solenoids in safety instrumented functions (SIFs). I turned to Riyaz to help me address the […]
In our continuing look at elements in the IEC 61511 process safety lifecycle, I uncovered an excellent presentation, Safety Instrumented Systems – Considering the Whole Loop, by Emerson’s Andy Crosland. You may recall Andy from a recent process safety seminar series in the U.K. Andy presents at Institute of Measurement and Control regional meetings from […]
I received a great question today about the safety integrity level (SIL) of a distributed control system (DCS). In this case, the question was specific to the DeltaV system: Can you please advise if the Emerson DeltaV DCS has a SIL rating i.e. ‘0’ or ‘1’? I understand that the DeltaV SIS has a SIL […]
