    SIL-rated FGS Vs. Typical FGS

    What make a SIL system saver than a non-SIL system are the fault-tolerant and diagnostic features that are inherent to a SIL system. These features reduce dramatically the PFD (Probability of Failure on Demand) of the system. SIL is the reciprocal to PFD. Thus, as your PFD goes down, your SIL...

    SIL-rated FGS Vs. Typical FGS

    SIL stands for Safety Integrity Level. It's a kind of rate that is attributed to Safety Instrumented Functions. And a safety Instrumented Function is composed of: a sensor, a logic solver, and a final element. In my case, the SIL-rated Fire Panel is the logic solver. Thanks.

    SIL-rated FGS Vs. Typical FGS

    Thanks cdafd, I don't know why these figures don't come up, but you can forget about them. The most important to me is to have more infos regarding differences between a typical Fire Panel and a SIL-rated fire Panel. Thanks for your help.

    SIL-rated FGS Vs. Typical FGS

    Hello all!!! I work as an I&C Junior Engineer and my Lead asked me to compare SIL-rated Fire panels to Standard Fire Panels. I did a bit of research, and would like more experienced people in the field to comment on my results. Please find attached here the file. Thanks in advance.

    Trip Concept

    Hello all, Could anyone tell me if Safety PLCs are exclusively designed to operate using a de-energize-to-trip concept? Most SIS systems are designed using a de-energize-to-trip concept. I tried, in vain, through IEC 61508/511 to see if I could find any paragraph or so dealing with the issue...

    Mercury disolved in water

    you are right IRstuff, the guy has just anwered me saying that he can't measure traces of Hg in water. The only way to do it is via a customized ($$$$) solution. I've also (that for JLseagull) received a negative answer from EcoChem. They just focus on gases. Thanks guys for help.

    Mercury disolved in water

    Correct IRstuff, that's what the article implies. But the thing is, TEKRAN has used its 2537A to monitor Hg in the Canadian Artic waters. It might not be exactely the same application like mine, still I've sent them an email to know more about their product. who knows!!!! Thanks a lot.

    Mercury disolved in water

    You are right IRstuff. What I'm looking for is an in-line device that can continuously measure the traces of Hg in water.It should be able to measure down to 0.001 mg/l of hg in my water. By the way, I am looking into the 2537 A from TEKRAN. It's supposed to be able to fill the bill. Any...

    Remote I/O

    Controlnovice, can you tell me the reason why you prefer a network communication provided by the vendor rather than a 3rd party one?

    Helllo Guys!!! I am an EIT (not yet familiar with DCS) and my supervisor asked me to compare the Remote I/O capabilities of different vendors. The thing is that I went through vendors documentation and I still can't decide the features that are really important for the sacke of comparison. I...
