For decades, the maintenance world has operated under a clear division of labor: Condition Monitoring (CM) teams identify faults, while Lubrication teams perform the proactive work required to prevent them.

Although both departments visit the same machines with a shared goal of reliability, they have historically worked in silos, often utilizing different tools and maintaining disconnected databases.

Today, SDT Ultrasound is proud to bridge this gap with the launch of the SDT340 LUBExpert Mode. By integrating the full intelligence of LUBExpert mode into our high-end SDT340 hardware, we are providing a unified reliability workstation that brings these two critical worlds together.

Why Lubrication is the Ultimate Proactive Action

The core of this innovation is driven by a simple but powerful truth: Condition Monitoring assesses the status, but lubrication secures it. While detection is vital for preventing catastrophe, prevention remains the superior strategy. When we monitor a bearing, we are essentially measuring the results of past actions or environmental factors.

In contrast, when we lubricate a bearing with the precision of the LUBrain algorithm, we are actively creating the conditions for its long-term health. By putting high-precision diagnostic power directly into the hands of the lubrication technician, we connect proactive and predictive segments in one natural, highly effective workflow.

Technical Superiority: A Laboratory in the Palm of Your Hand

The SDT340 LUBExpert Mode is designed for the modern reliability professional who refuses to compromise on data quality. Utilizing High Signal Resolution (HSR) technology, the device captures extreme detail with a measurement resolution of up to 256 ksps. This level of precision, coupled with acquisition times that can extend up to 600 seconds, allows for the reliable analysis of slow-speed assets, a task that often leaves standard systems struggling.

The device functions as a portable laboratory, capable of managing ultrasound, vibration, temperature, and rotating speed measurements simultaneously. For ultimate flexibility, users can choose their signal recording depth: they can save the full time waveform for every injection step to conduct deep analysis, or focus on the “Initial and Final” measurements for efficient reporting.

Task Optimization: Doing More with Existing Resources

The SDT340 LUBExpert Mode empowers your lubrication team to collect lab-quality Condition Monitoring data during their standard greasing routes.

Thanks to the RS2T multi-role sensor, there is no longer a need to switch hardware in the field. The sensor functions as a LUBEsense for the guided lubrication process while simultaneously capturing the time waveforms and spectra required by analysts. This approach creates a comprehensive “History of Health” for the asset with zero additional man-hours, significantly increasing your plant’s monitoring coverage.

Intelligence Guided by the LUBrain Algorithm

The LUBExpert mode is an intelligent assistant powered by the LUBrain algorithm, which makes real-time decisions based on live measurements.

  • Guided Mode: The instrument steers the user step-by-step through the entire greasing process.
  • Stabilization: It automatically calculates stabilization times and injection steps to ensure consistent, dependable comparisons between every task.
  • Free Mode: For specialists who need to perform advanced investigations, Free Mode provides manual control while still monitoring the development of the measurement and logging every detail for full traceability.
  • Data Integrity: To ensure accurate records, the system now requires the user to enter the number of shots added before the interface allows them to continue, eliminating the risk of “forgotten” or estimated data in the field.

Seamless Integration with UAS3

This hardware evolution is backed by a massive update to our Ultranalysis® Suite 3 (UAS3) software. Now utilizing PostgreSQL 18 for enhanced performance, the software allows you to seamlessly convert legacy SDT270 and LUBExpert tree structures into the SDT340 format. All lubrication trends, grease quantities, and diagnostic signals are now housed in a single database, providing a truly holistic view of your maintenance strategy.

Conclusion: Bridging the Gap to Zero Downtime

The transition from a standalone lubrication tool to the integrated SDT340 LUBExpert Mode represents a fundamental shift in how we approach asset management. By merging diagnosis and action into a single workflow, we remove the guesswork that has historically plagued maintenance departments.

This evolution ensures that every lubrication task is backed by high-resolution data and every diagnostic finding is met with a precise, proactive response. As we move toward a future of zero unplanned downtime, the SDT340 stands as the ultimate “Jack of All Trades” workstation, providing the clarity to understand an asset’s current status and the capability to secure its future.
