Is increasing oil cleanliness on your 2021 to-do list? Oil contamination continues to be one of the biggest causes of component failure and productivity declines. Oil cleanliness starts at the beginning with inspecting and filtering your new and incoming oil.

For more complex analysis, analysts require further tools to diagnose better the issues. Playing the TWF as an audio file is a good way of listening to the vibration to potentially hear knocking, pinging or high frequency whistling, denoting a problem to further diagnose, as if you were actually beside the machine.

Gear faults typically occur in the teeth of a gear mechanism due to fatigue, spalling, or pitting. These can be manifested as cracks in the gear root or removal of metal from the tooth surface. Gears are the main elements of power transmission in many industrial applications and are subjected to significant stresses and loading.

Galvanic isolation was developed as a response to galvanic paths and subsequently, the signal interference they cause. A galvanic path is defined as a path in which there is a direct electrical connection between two or more electrical circuits that allow current to flow..

Water is one of the most destructive contaminants faced by industrial maintenance departments. Some systems may be more tolerant to water, while others can be more sensitive. Some manufacturers have set limits as low as 30 ppm. Best practice would tend to indicate that it is beneficial to keep water contamination at the lowest level possible..
