🔧 Sensor vs Transducer vs Transmitter — Know the Difference! ⚙️📡
In instrumentation, these three terms are often mixed up, but each has a different role:
🌡️ Sensor: detects the physical quantity
⚡ Transducer: converts it into a usable signal
📶 Transmitter: sends a standardized signal to the control system
Think of it as the measurement chain:
Sense → Convert → Transmit
Understanding this difference is essential for anyone working with PLC, SCADA, process control, and industrial automation. 🚀
