The SDT LUBExpert Ultrasound tool is an affordable tool to help you grease bearings right. The Lube expert allows you to monitor bearings as lubrication is being added. A bearing with not enough grease is “loud” as is a bearing with too much grease.

The SDT LUBExpert allows you to “listen” to the bearings while the grease is being added (acoustic lubrication). In addition you are monitoring the Ultrasound levels on the display and the Lube expert will guide you through the process. Using Ultranalysis Suite 3 software you can create databases and routes, add alarms, trend measurements, monitor grease quantities and more.

LUBExpert Dynamic Option

Collect valuable, dynamic condition monitoring data with LUBExpert Dynamic and analyze it in UAS3. While in the ultrasonic lubrication process, the lubrication team can collect and view data in the Time and Frequency domain. They can remove silos between them and the condition monitoring team.
