Vibration testing plays a vital role in industrial settings because nearly all of the machinery vibrates due to its normal functioning. The purpose for testing, however, is to pinpoint any changes during the vibrational modes that may or may not occur during startups, shutdowns and normal functioning.

Small changes within the equipment can be determined through vibration testing, indicating that a component is wearing or some kind of valve may need to be changed or maintenance needs to be done to a seal. However, changes in vibration do not always indicate an impending massive break down or component damage. Rather, the modifications actually suggest that minor conditions have changed and it could be a couple of weeks or a couple of months before a part will break.

Training and experience are required to accurately read and translate data received from measurement devices, and then correspond that information to the machine. According to what equipment is being tested, the tools utilized to take measurements of vibration will differ. An extremely large and dangerous machine will likely require a large, ...
... permanent monitoring system that takes constant data on the machine. However, a smaller and less risky piece of equipment can be tested manually utilizing a small portable device.

When it comes to vibration testing, a trained professional will have a range of unique devices at his disposal for data collection and analysis. Each professional should have small, handheld devices that can travel from site to site and these will have a variety of sensors. On top of that he will probably install online instruments to machines that demand constant monitoring. These instruments generally come with features that allow for alarming and wireless transmission of collected data. For ultimate vibration monitoring, a number of sensors will also be available for use on these permanent monitoring systems. These sensors vary significantly depending on their purpose; however, some will have added features that create a higher level of safety.

The key to saving money on industrial sized equipment lies in performing vibration testing and maintaining it. By carrying out this special type of testing, you will be able to discover any areas that are causes new loss of energy or areas that may be beginning to fail. By taking the proactive approach to machine maintenance you will save money on parts and time spent fixing worn out pieces. You will be able to circumvent shut downs that hinder your ability to make money and you can avoid costly machine failures that are costly in both time and money.
