Recently, SDT International took up this challenge on a rotating machine with a rotation speed of 8 RPM.
More than a week earlier, the maintenance department of a world-renowned company had detected unusual noise on a strategic production asset. The sudden stop of this machine would have led to the complete shutdown of the production site. Not to mention the financial cost of replacing these 4 bearings, the time required for the procurement of these specific bearings and the cost of the maintenance labour.
There was a dual stake here: control the condition of these bearings and attempt to detect the origin of this noise.
A diagnosis could be issued using the new ultrasonic measuring instrument, SDT340, and its FOCUS mode that can generate sampling frequencies up to 256 K samples per second.
