Why is acceleration enveloping useful for rolling-element bearing diagnostics?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eBearing defects can generate repetitive high-frequency impacts. Enveloping analysis extracts the amplitude modulation associated with these impacts, helping engineers identify developing bearing damage before it becomes obvious in overall vibration readings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2. Does a 100 mV\/g sensitivity mean the sensor always outputs 100 mV?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The 100 mV\/g value represents nominal sensitivity at 80 Hz. Actual signal amplitude depends on the applied acceleration, frequency response, operating conditions, and sensor output bias. The specified bias voltage must also be considered when interpreting the electrical signal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3.

Should I replace only the accelerometer when upgrading a Trendmaster Pro monitoring point?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot necessarily. Review the ProTIM option, channel type, sensor mounting arrangement, and monitoring input configuration.
