Proximity Sensors Explained: Inductive vs Capacitive vs Photoelectric
Inductive, capacitive, and photoelectric sensors all answer the same basic question, is something there?, but they sense completely different physical properties, and picking the wrong type is one of the most common causes of unreliable machine behavior on the plant floor.
What Is SCADA? Architecture, Components, and How It Works
SCADA lets a single operator monitor and control equipment spread across an entire plant, pipeline, or utility network — here's what the acronym actually means, the five components every system shares, and how it differs from a standalone PLC or a full DCS.
