Resonance is a condition where a machine is operating at a frequency close to or at the natural frequency of its structure. This condition excites the structure and causes high amplitude vibrations; this will show up as a “hump” at the resonant frequency in the spectral data…
read moreMachinery in industrial environments typically generate a lot of noise. Other than being very loud, these noise emissions can sometimes provide clues to the condition of a particular machine. Measuring ultrasonics can be useful in detecting: • Steam and air leaks • Lubrication issues •…
read moreRolling element bearings are used in all sorts of rotating applications. Unfortunately, because of poor machine setup and maintenance, fewer than 10% of bearings reach their intended design life; this is because even marginal increases above the maximum allowable load on a bearing can dramatically…
