SDT340 LUBExpert
Condition monitoring assesses — lubrication optimizes
One device for bearing lubrication and diagnostics: SDT340 combines ultrasonic condition monitoring and intelligent lubrication management in a single tool. The LUBrain algorithm eliminates both over- and under-lubrication.
Why lubrication is the most proactive maintenance action
Monitoring and lubrication teams traditionally worked separately: one diagnosed, the other serviced. The result — information gaps and equipment failing between visits.
SDT340 LUBExpert turns every routine lubrication visit into a full condition-monitoring session — with no extra labor.

Technical parameters
SDT340 in the field
RS2T sensor — one for every task
The multi-role sensor eliminates equipment swaps in the field. The specialist uses a single sensor for the entire route.
Key benefits
SDT340 LUBExpert shifts the maintenance approach — from predictive to proactive
One device — two teams
The lubrication operator collects full diagnostic data during the routine route. Coverage grows without growing headcount.
No over- or under-lubrication
LUBrain stops lubrication at the optimal moment. 36%+ of bearing failures result from improper lubrication.
Slow-speed equipment
Recording up to 600 seconds. Gearboxes, conveyors, and fans below 100 RPM — data remains reliable.
Historical data is preserved
UAS3 imports archives from SDT270 and previous LUBExpert units. Accumulated data is never lost on upgrade.
UAS3 integration
SDT340 LUBExpert is fully integrated with UAS3 — the data management platform from SDT Ultrasound.
PostgreSQL 18
Improved performance when working with large data volumes
Unified database
Lubrication trends, pump counts, and diagnostic signals in one place
Data conversion
Import archives from SDT270 and earlier LUBExpert versions without losing information
Frequently asked questions
1Can the SDT340 be used without LUBExpert mode?
Yes. The SDT340 is a full-featured, multi-function ultrasonic instrument. LUBExpert is an additional mode that is activated when needed.
2Is data import from the SDT270 supported?
Yes, UAS3 supports converting data from the SDT270 and earlier LUBExpert versions without losing the archive.
3Does the device work with slow-speed equipment (under 100 RPM)?
Yes. Recording times of up to 600 seconds are specifically designed for slow-rotating assets — gearboxes, conveyors, fans.
4How does the SDT340 LUBExpert differ from the standalone LUBExpert system?
LUBExpert as a standalone system is a specialized tool for lubrication only. The SDT340 is a multi-function diagnostic instrument in which LUBExpert runs as one mode alongside full ultrasonic and vibration diagnostics on a single device.
5Do you provide training for the SDT340 LUBExpert?
Yes, KEG TRK trains specialists on-site at the customer and at our training center in Kazakhstan.
