🔍 Key Concepts

• Difference between temperature sensors and vibration sensors • What an accelerometer measures in basic physics terms • Meaning of the general term transducer in instrumentation

💭 Think About

• Ask yourself: which device is specifically designed to measure changes in motion, shock, or vibration on rotating machinery? • Which option names a broad category that could include many types of sensors, and which option names a very specific sensor type? • Which choice is clearly related to measuring temperature rather than vibration?

✅ Before You Answer

• Eliminate any device whose primary purpose is temperature measurement rather than motion or vibration • Identify which option is a general class of device instead of a specific vibration-measuring instrument • Consider which device is commonly mounted on bearings or casings of high‑speed rotating equipment to monitor vibration levels
