Hi,

In one of the project, i have to measure the tank level. And i have got got clear directions that it must be SIL3 compliant.

How should i design my system?

1. Which type of PLC?
2. Which type of instrument?
3. Wiring details?
4. Is it required to have multiple level transmitters?

Can anyone help me

 

Hi,

-Visit:
ab.com/catalogs

-in the section safety products download the pdf file for the sub sections "General" and "Principles".

It is about 70 pages and gives you an understanding of the issue.

Good luck!

 

i guess the PLC they mentioned is Triconex. and what about the instrumentation part.

can anybody explain me in detail about the design considerations?
