Before taking full advantage of ultrasonic technology, many of us go to great lengths to identify a failing condition in our anti-friction bearings. We look for either the smallest change in movement or a slight increase in surface temperature to tell us that something is not working properly. Could there be a more obvious measurement that will tell us that not only is something wrong, but more importantly, that will also help prevent the failure from occurring in the first place? Yes, and using ultrasonic equipment and analysis, it is so obvious! It is in the bearing’s name - Friction!

More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..

Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

There are many faults that cause a rotating component to breakdown and fail, some of the most common being misalignment, unbalance and soft foot. One of the most common faults that cause a component to breakdown are bearing defects.
Why would a company carry out condition monitoring programs?

As predictive maintenance teams in industrial facilities strive for a more complete picture of their equipment’s health, high frequency vibration measurements have become a crucial addition to identify faults such as motor and pump bearing defects and gear tooth inconsistencies in high-speed gearboxes. As a result, there is an upsurge in demand for vibration sensors with a high frequency response.

Studies show that 50 to 70% of all equipment failures can be directly traced to a lubrication-related issue, most of which can be found with oil analysis.
A small number of semiconductor manufacturers have overcome the noise, bandwidth and g-Range shortcomings commonly associated with MEMS sensors used in Condition-based Monitoring (CbM) by producing several medium and high-performance MEMS vibration sensors with the latter being comparable to piezo accelerometers.
