A pressure transmitter has (\lambda_DU = 150) FITs (failures in time: (1 \textFIT = 10^-9 \textfailures/hour)). Proof test interval = 2 years (17,520 hrs). Neglecting common cause, what is the PFDavg for a 1oo1 configuration? Solution: (150 \times 10^-9 \times (17520/2) = 150e-9 \times 8760 = 0.001314) (SIL 2).
Passing the CFSE exam is notoriously challenging. It does not test rote memorization; it tests applied judgment. This guide provides a strategic roadmap to conquer the exam and earn the right to put "CFSE" after your name.
