Level switch as part 2oo3 voting
Level switch as part 2oo3 voting
(OP)
Hi
Is it a good idea to use level switch as part of 2oo3 voting where the other two devices are transmitters.. in this case , if the switch fails, we will not know and we will end up having two devices (2oo2) configuration.. is this correct ? Can anyone add more comment from experience on this type of configuration please
Thank you

On the other hand, assuming that this is for a Safety Instrumented System (SIS), limits switches have a higher failure rate when compared with process transmitters.
With that in mind, perform the SIL calculation and determine if you met the SIL level required.
