All the Difference - LUBExpert's 4CI

4CI Trend

image82

  • Before 4CI, ultrasound inspectors trended ultrasound data based on a single decibel measurement taken at an arbitrary point in time. Capture the measurement at the wrong time and the defect was either missed or amplified beyond reality. 4CI allows inspectors to set the acquisition time prior to capturing the measurement. The result is a more representative and accurate collection of data. 

Condition Indicator 1 – Overall RMS

  • CI 1 averages the entire sample captured and returns a single RMS decibel value. The Overall RMS is used to trend the condition of a bearing throughout its life-cycle.

Condition Indicator 2 – Max RMS

  • CI 2 is the highest of the sub-RMS's calculated every 250ms. Compared with the RMS, it is used to find out if the signal is stable or if it varies but it is also not very sensitive to the detection of impact.

Condition Indicator 3 – Peak Value

  • It is the maximum instantaneous value recorded during the measurement cycle. It is used primarily for impacts produced by early stages of failure in bearings and gears.

Condition Indicator 4 – Crest Factor

  • CI 4 is the ratio between the Peak Value and the RMS value. When an asset is entering failure mode, the CF value will spike even if the RMS remains moderate. The CF levels drop as failure stage advances because the Peak Value remains high as the RMS advances.

Regular Maintenance Safeguards Plant Health

  • A major part of keeping equipment running smoothly involves regular maintenance, ensuring that machinery is correctly lubricated and properly aligned.

Avoid Costly Downtime

  • When shafts or belts on rotating equipment are misaligned, the risk of costly unplanned machine downtime rises dramatically.

Do the Job Right

  • Misalignment damages the bearings, seals and couplings whilst lubrication problems are very often traced to over lubrication or seals that have been compromised because of misalignment.

Save Your Plant

  • Simply replacing a seal will not stop future seal failures and associated loss of lubricant, only correcting the misalignment will solve the problem whilst continued bearing health can be safeguarded through lubricating on condition rather than by routine.

Lubexpert - The 5 R's

Right Lube

image87

  • Different applications require different lubricants. Which one is the right one? LUBExpert’s onboard assistant helps you select the correct grease and reminds you of the bearing’s maximum capacity. 

Right Location

image88

  • With potentially thousands of assets to manage, how can you be sure you’re greasing the right bearings? LUBExpert’s onboard assistant guides you through your plant using UAS’s tree structured navigation. 

Right Interval

image89

  • Whether you lubricate on a calendar or condition based schedule, LUBExpert and UAS alert you when bearings are due for re-lubrication. Alarms triggered by SDT’s evolutionary 4 CI make sure the “squeaky wheel” gets greased on time. 

Right Quantity

  • Over and under lubrication are to blame for most lubrication related failures. LUBExpert’s onboard assistant continuously calculates friction levels between shots of grease, advising you to add more – or stop when optimal friction levels are reached.

Right Indicators

  • LUBExpert delivers confidence to the task of re-greasing bearings. The onboard assistant guides you smoothly through the task and concludes with a GOOD, BAD, or SUSPECT result. UAS then reports on before and after, quantity of grease added per point and total grease consumed.
