The on-site measurement data of motor vibration does not match the system monitoring data
Thread Content
A new centrifugal oil transfer pump was installed. Through on-site monitoring, the motor’s vibration was measured at 0.7 mm/s, but the system’s monitoring data showed 7 mm/s. We replaced the monitoring probe with one that works properly on other motors and conducted further measurements; the result remained the same. It can be concluded that the actual vibration of the motor is normal, yet the system’s monitoring data is always 10 times higher than the actual value – for some reason
Is the unit for system detection data mm/s? Our unit is different; the system uses peak values, while the actual measurement is in mm/s ； A difference of 0.7 times ；
I’ve encountered similar situations; seeking advice as well. :)
We encountered a problem: when the motor vibration detection probe was pulled out slightly, the vibration data became normal. Could it be that the hole is too deep?
