Steam Pipeline Water Hammer: 80% of Accidents Are Caused by These Common Mistakes

Instrumentation /

In the field, many operators have experienced this moment: despite following procedures, the moment the steam valve is opened, a dull “bang” is heard from the pipeline, the steel pipes shake, and white steam rises from the flanges… This is a classic case of steam pipeline water hammer. If not addressed immediately, it can cause

What is the Difference Between Sensors and Transmitters?

Transmitter /

In modern industrial automation systems, “sensors” and “transmitters” are ubiquitous. They act as the sensory and nervous systems of automation: one is responsible for “sensing the world,” while the other transmits the information. Though they often work together, their functions and principles differ significantly. Today, let’s discuss the key differences between sensors and transmitters. 1.
