Why Plants Use Multiple Transmitters for the Same Measurement  Multiple transmitters for a single process variable are not redundancy for redundancy’s sake  they are deliberate engineering choices to control risk, maintain production continuity and meet functional safety obligations. In continuous and semi-continuous process industries (oil & gas, petrochemical, fertilizer, power), a single lost or biased … Continue reading Redundant Transmitters Explained: Reliability, Voting Logic and SIL for Instrumentation Engineers
