A New Approach to pH Sensor Implementation


September 2016 Section Meeting

Many types of pH sensors are on the market and most are designed and marketed with specific strengths.

SIL calculation free tool for Android devices



ISA Group on LInkedin —  This APP by Pierluigi Meloni, Controls Engineering Manager at GE Oil & Gas, allows the SIL (PFD and RRF) calculation of a SIF modelled as input+logic solver+output.

It also calculates the MTTFs as per ISA-84 [Electrical/Electronic/Programmable Electronic Systems (E/E/PES) for Use in Process Industry Safety Applications] formulae.

The inputs for the calculations are the failure rates in FIT (the app provides a converter from flr/hrs) and a simple wizard to calculate Lambdas from PFD, Proof test interval and MTTF.

Additionally, it calculates, given the HFT and the SFF, the architectural constraints supporting both IEC-61508 and IEC-61511 tables. Continue reading
