To the one who is doing a school project on bearing wear: As a Navy veteran, we used DVSIs for monitoring bearing wear and approximate length of time the bearings will last. I'm not sure if you can get a hold of them, but may I suggest that you try and contact Performance Monitoring Team of San Diego, CA or PMT, Norfolk, VA. They are only two teams in the Navy (that I am aware of) that use these type of devices. They are used to determine life of bearings on certain pieces of equipment on Naval Ships as well as utilizing Thermal Graphic Image devices, used to determine the stability of breaker panels for these devices. Good Luck!
