What is the difference between an accelerometer and a probe?
Thread Content
The standards related to mechanical pumps always mention instruments for measuring vibration; currently, the main ones are accelerometers and probes, but what is the difference between them? In what situations are they applicable respectively? What are the key phaser and one-event-per-revolution used for?
An accelerometer is presumably a device for measuring acceleration; a probe is simply a sensing element. Keyphasor refers to key phase, and it seems to be used for monitoring and diagnosing the condition of machinery. One-event-per-revolution means that an event is triggered once per rotation I don’t understand. You can check the GE Bently documentation for the instrument panel of the unit……
Correct answer. Finally, does one-event-per-revolution have something to do with measuring speed/frequency? One event per revolution, right?
one-event-per-revolution must be a laser speed detector; our company purchased a set of dynamic analyzer equipment this year, which includes the aforementioned component.
What are left and right for an accelerometer? Is it lateral vibration? If so, what is the difference from a regular vibration probe?
The accelerometer should be used to measure the vibration of the housing, such as the gearbox housing……
