Question 1

Which sensor technology is most commonly used in online oil analysis systems to detect metallic wear particles in real time?

Accepted Answer

Inductive wear debris sensor

Answer

Inductive wear debris sensors detect ferrous and non-ferrous metallic particles passing through a magnetic field, enabling real-time condition monitoring.

Question 2

In a computerized maintenance management system (CMMS), what is the primary purpose of linking lubrication tasks to equipment hierarchy?

Accepted Answer

To enable traceability and scheduling of PM tasks at the asset level

Answer

Linking tasks to equipment hierarchy in a CMMS enables precise scheduling, traceability, and reporting of preventive maintenance activities at the individual asset level.

Question 3

A vibration analysis route collected via a handheld data collector shows a spike at 1× running speed. What lubrication-related condition could this indicate?

Accepted Answer

Imbalance aggravated by inadequate lubrication film

Answer

A 1× running speed vibration peak can indicate imbalance, which is worsened when inadequate lubrication increases friction and load on rotating components.

Question 4

Which digital tool allows lubrication technicians to scan a machine tag and immediately retrieve its lubrication specification, interval, and history?

Accepted Answer

QR/barcode-linked CMMS mobile app

Answer

A mobile CMMS app with QR or barcode scanning links each machine tag to its complete lubrication record, making field access to specifications instant.

Question 5

What does a rising Karl Fischer (KF) titration value trend in periodic oil samples from a gearbox indicate?

Accepted Answer

Increasing water content in the lubricant

Answer

Karl Fischer titration quantifies water content; a rising trend indicates progressive water ingression into the gearbox lubricant.
