The Anderon meter is a device used to measure bearing vibration, often to help assess potential noise concerns. Simply put, the higher the vibration velocity measurement, the noisier the bearing is. The Anderon meter readings are separated into 3 difference frequency bands. Low, medium, and high. The low frequency band would be 50 to 300 hertz. Medium, 300 to 1800 hertz. The high band would be 18 to 10,000 hertz.
The Anderon meter can be used to measure the noise levels of assembled bearings. Using the Anderon meter, the can bearings are pre-loaded on the outer ring, and the inner ring rotates at roughly 1800 RPMs. With the outer ring being stationary a probe is lowered to the point where it contacts the outer ring’s surface. This reports vibration readings, and translates those readings into the 3 frequency bands mentioned earlier. This allows engineers to compare the noise levels of the.
