A safety instrumented system (SIS) is a set of hardware and software controls that are used to take the process to a safe state when pre-determined conditions are violated
A SIS is separate from the basic process control system and is designed to provide protection for critical process systems, such as refineries, chemical, nuclear facilities.

I Am Happy to watch Your Videos and to say that i just seen that your the alumni of VESIT I Also Currently Pursuing In final Year In VESIT And It's Proud To Seen Some Of Our College Senior Is doing Well For student. Keep Doing Best Of luck..!!
1st time watching such a great video.. keep it up.. really excellent
Thank you so much 😀
Very good explanation.
Thanks a lot.
Very good explanation just a little correction about the SIF assembly. Usually the SIS is not involved in controlling functions (like PIC) but just in simple acting (ON/OFF)
I agree with you in this. Also, safety action and control action needs to be segregated as they are two different layers of protection.
Fantastic information.
Please make comprehensive video on datasheets of flow,level, pressure and temperature instruments. How to make datasheets of these instruments.
I have seen your video titled how to make datasheet but it is basic and generic.
Thanks in advance
Good explanation
I think 1 Sif=sensor+logic solver+FCE
SIS=No. SIF wrt there safety events
And SIL rating given to SIF,
Not individual component , we only represent this component is suitable to work in this SIL rating
Sir I want to have this course
Good video.... What is PIC in rhombus symbol?
Thanks.
In P&ID It denotes it comes under SAFETY scope .
Good video
Good video....Is PHA and HAZOP same?
@ProductProcess HAZOP is a type of PHA. Common methods for PHA include “bowtie” analysis, Fault Tree Analysis (FTA), Failure Mode and Effect Analysis (FMEA), Hazard and Operability studies (HAZOPs) and “What If” analyses.
@@ProductProcess Thanks....

Hope this helps 😊
where to check SIL ratings of particular instruments
Ask vendor the SIL certificate if the instrument will be installed in SIS loop.
Correct . Vendors have SIL data and certificates for their instruments
