In the world of instrumentation, theoretical knowledge is like the wrench in your toolkit — it may seem insignificant, but when it fails, it can bring everything to a halt! Whether you’re preparing for an entry-level certification or simply aiming to strengthen your foundational knowledge for daily operations, the concepts of circuit diagrams, sensor principles, […]
Reed switch level sensors and magnetostrictive level sensors are two common technologies used for liquid level measurement. These two sensors differ in their operating principles, applications, and performance characteristics. Below is a comparison of the two. 1. Operating Principle Reed Switch Level Sensors: Reed switch level sensors operate based on the interaction between a reed

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

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.
