Use a handheld vibrometer (Times TV260 model) to detect the vibration of the equipment. Is the measured speed a valid value? Is the measured displacement peak-to-peak?
General vibration meters are like this.
Vibration meter functions: 1. Times TV260 pen-type vibration meter is used for vibration measurement of motors, fans, pumps, compressors, machine tools and other equipment, and for preventive inspection of mechanical equipment failures. ; 2.Measurement data retention function ; 3. Automatic shutdown function ; 4. Automatic switching of three parameters for measurement ; 5. Single button control, simple operation ; 6. Low power consumption. Function: 1.
