Safety Instrumented Systems (SIS) are installed in Process Plants to mitigate process hazards by taking the process to a “safe state” when predetermined set points have been exceeded or when safe operating conditions have been transgressed. Each hazard that requires the use of an SIS must be assigned a target SIL level. This article serves as a high-level summary as to how SIL levels are determined for process applications.

If you have the popular APACS Control System, you also have a decision to make. APACS was declared "mature" in 2010 with support only lasting through 2020. This article will discuss phased migration options from APACS to PCS 7.

Current technology abounds, even in industrial work environments. However, there are inherent risks to using smart technology as any internet-connected device can be hacked. We need to be smart about how we implement smart devices.

Perhaps one of the hardest facets to quantify in the industrial world is the monetary impact of unexpected downtime (UDT).

One of the most common Flow Measurement issues is incorrectly sized flow meters. Learn how upstream and downstream pipe diameters play a role in this measurement.
