Correct pressure and other process sensor measurements are necessary for reliability, product quality, maintenance, process safety, and cyber security. These devices can be incorrect for unintentional or malicious reasons. January 13, 2023, Abhishek Sharma published the ISA blog – “The wisdom of correct pressure measurements”. It is a good blog but doesn’t address all of the issues. Consequently, I have provided some additional thoughts from my time in nuclear plant Instrumentation and Control (I&C) and control system cyber security that were not addressed in Abhishek’s ISA blog. The cyber security issues that affect pressure measurements are common to other process measurements. If you can’t trust your pressure and other process measurements, you have no cyber security, safety, reliability, resilience, or situational awareness.

I agree Joe, if the data is not trustworthy, then the resulting decisions made using that data will also be questionable.
