2S8: HD Technology – A low RPM case, 3 years pre-warning time

Tim Sundstrom, Manager of Strategic Sales & Application, SPM Instrument


In this case study we will follow a bearing from the earliest damage indication to a severe damage during three years. The presentation will cover the basic concept of HD Technology and how the HD technology can extend the pre-warning time dramatically.
The bearing is rotating continuously with a relatively low speed (16 RPM). The presented application is from a fertilizer plant and is one of the absolutely most critical application found in this operation. An innovative tool to show information from several hundred spectrums in one picture will be demonstrated among other advanced tools.
