For decades, industrial ultrasound has been a major asset in predictive maintenance, but its complexity and cost have often limited its use to certified experts.

High-end detectors are essential for in-depth diagnostics, but prove complex for widespread routine inspections. The reality of modern reliability demands a simpler set of tools for frontline personnel.

SDT’s Checkers range is designed to be that essential “First Line of Defense Against Failure,” adhering to a Focused, Simple, and Affordable philosophy. This approach directly enables Operator-Driven Reliability (ODR), involving technicians in rapid inspections.

The lubrication crisis: 80% failure rate

The most pressing challenge is the root cause of rotating asset failure. It is estimated that 80% of all premature bearing failures are attributed to inadequate or inappropriate lubrication. This alarming statistic stems from common mistakes: relying on subjective methods (“listening alone”) and scheduling lubrication based solely on operating time, ignoring critical factors such as friction or load. Over-lubrication and under-lubrication inevitably lead to increased temperatures and wear.

The LUBEChecker takes lubrication from approximation to quantitative precision. It eliminates subjective listening by providing an accurate measurement, allowing technicians to monitor the minute change in friction when applying lubricant. The operator stops lubrication as soon as the decibel reading stops decreasing and begins to increase slightly, ensuring the optimal fill level and avoiding costly over-lubrication.

Targeted detection and quantifiable ROI

In addition to the LUBEChecker, the strength of the range lies in its specialization. Instead of relying on a single complex device that may be incorrectly configured, this range offers tools dedicated to key applications :

  • LEAKChecker: Compressed air and gas leaks are a waste of energy. The LEAKChecker is a specialized tool that allows teams to quickly detect leaks. Combined with the LEAKReporter application, ultrasonic measurements are converted into financial impact estimates, allowing managers to generate quantifiable reports proving return on investment (ROI).
  • TRAPChecker: Dedicated to monitoring steam traps and valves to detect turbulence, helping to prevent significant energy losses.
  • TIGHTChecker and HATCHecker: Ensure the integrity of seals and enclosed spaces.

By deploying these devices, organizations can rapidly expand their monitoring coverage, maximize the effectiveness of their expert analysts, and integrate accurate, data-driven decisions at the front-line workforce level.
