Can you compare the overall level measured from three different types of systems and assume they will give you the same reading for the same level of vibration?

When measuring vibration levels, it is essential to consider that different systems may have varying sensitivities, measurement ranges, and calibration standards, which can lead to discrepancies in the readings. Each type of system—whether it be accelerometers, velocity sensors, or displacement sensors—responds differently to vibrations based on their designed purpose and dynamics.

Because of these differences, it is not valid to assume that they will provide the same result when measuring the same vibration level. For instance, one system may be optimized for detecting high-frequency vibrations, while another may be better suited for low-frequency feedback. Additionally, factors such as mounting techniques, environmental conditions, and even the inherent characteristics of the materials being tested can affect the measurement outcomes.

By highlighting the likelihood of differences in reading due to these factors, it becomes clear that comparing the overall levels from varying systems without consideration of their unique characteristics would lead to inaccurate conclusions. Therefore, it is prudent to approach such comparisons with caution, recognizing that the systems' design and calibration can significantly influence the results.
