Does pressing the handheld vibration meter firmly against the pipe affect the results?
Thread Content
When we measure vibrations, we place the vibration sensor on top of the pipeline, right? Does this count as providing support to the pipeline, reducing its vibration, which in turn results in a lower final value?
I think it has some impact. However, most of our pipe tests are conducted to determine which, between the equipment and the pipes, vibrates more, in order to identify the cause of the vibration. And if, when testing the pipeline, more force is applied and the vibrations are reduced, it generally indicates that the pipeline needs to be secured or is experiencing resonance; in such cases, adding supports or reinforcing it will suffice.
If I were to measure whether the vibration acceleration of a pipe exceeds 8, wouldn’t the result be false?
Vibration has a corresponding direction; if the vibration of a pipe is up and down in amplitude, then the upper direction should be chosen. Test it using the methods specified in the instructions for reference.
Small tubes have an impact, while large tubes do not
When using calipers, applying force can affect the measurement values, let alone vibration.
