What Problems Can the QI2500 Detect?

Vibration is one of the earliest indicators of mechanical problems in rotating equipment.

The QI2500 continuously measures vibration and temperature to identify changes that often signal developing faults.

These insights allow maintenance teams to plan repairs before unexpected failures occur.

Bearing Wear and Bearing Failure

Bearings often show increasing vibration long before they fail.

The QI2500 can detect rising vibration levels and characteristic frequencies associated with bearing wear, allowing maintenance teams to schedule replacement before catastrophic failure.

Common symptoms detected:

• Increasing vibration velocity
• High-frequency acceleration
• Rising temperature

Imbalance

Imbalance occurs when rotating components no longer spin evenly.

This can happen due to:

• Material buildup
• Worn components
• Improper repairs
• Manufacturing tolerances

Imbalance typically appears as strong vibration at the machine’s running speed.

Left uncorrected, imbalance accelerates bearing wear and can damage shafts and couplings.

Misalignment

When shafts are not properly aligned, excessive forces are placed on bearings and couplings.

Misalignment often produces elevated vibration levels and harmonic frequencies.

Early detection can prevent:

• Coupling failure
• Premature bearing damage
• Shaft fatigue

Mechanical Looseness

Loose mounting bolts, worn mounts, or structural issues can allow components to move during operation.

This condition often produces irregular vibration patterns and elevated broadband vibration.

Detecting looseness early can prevent severe machine damage.

Gear Wear

Gearboxes often develop vibration signatures as gear teeth wear or become damaged.

The QI2500 can detect increasing vibration levels and frequency patterns associated with gear mesh problems.

Early detection allows maintenance teams to inspect and repair gear systems before major damage occurs.

Developing Machine Faults

Even when a specific failure mode is not immediately obvious, increasing vibration trends often indicate that something in the machine is changing.

Trending vibration levels over time allows maintenance teams to:

• Identify machines that are degrading
• Prioritize inspections
• Schedule maintenance proactively

Establish a Baseline for Your Machines

Every machine has its own normal vibration signature.

The QI2500 allows you to establish a baseline so future changes become immediately visible.

Instead of guessing whether vibration is normal, you will have real data for comparison.

Turn Machine Data Into Maintenance Decisions

The goal is simple:
detect problems early so maintenance can be planned instead of reacting to breakdowns.

The QI2500 provides the measurements needed to understand the condition of your machines and take action before failures occur.
