Loop signature 25: Tuning part 3 - Results of tuning a particular simple self-regulating process by several different methods.
October 2024, Editor's Choice, Michael Brown Control Engineering
A couple of SWAG methods of tuning were given in the previous Loop Signature article. I have tuned a simple self-regulating process using those methods, and two other tuning methods, one of them being the sophisticated Protuner tuning package, which is the system I employ. The tests were performed on a very accurate and powerful simulation package, and the results are compared below.

Inspection system for leak detection in valves in hazardous areas
October 2024, Valves, Actuators & Pump Control, Extech Safety Systems
Leaking valves in industrial plants not only lead to loss, safety risks and possible contamination and pollution, but also result in high economic costs. Therefore, valves in hazardous areas require regular proper inspection and preventive maintenance to ensure their functionality.

Reducing the carbon footprint by eliminating SF6
October 2024, Electrical Power & Protection, Schneider Electric South Africa
SF6 is a manmade gas widely used in the electricity industry for insulation and current breaking, and in medium- and high-voltage equipment. Unfortunately it is also the world’s most potent greenhouse gas. One important step is implementing SF6-free equipment in today’s modernised grid infrastructure.
