Areas of practice

Connected disciplines.
One reliability decision.

Condition monitoring is strongest when signals, machine behaviour, maintenance history and operating context are considered together.

01

Vibration Analysis

Time waveform, spectrum, phase and machine-response evidence interpreted in operating context.

02

Condition Monitoring

Routes, trends and multiple technologies translated into clear equipment condition decisions.

Explore discipline →
03

Reliability / RCM

Failure-mode thinking and maintenance priorities shaped around risk, consequence and evidence.

A practical decision path

Measure carefully.
Interpret in context.
Act with purpose.

Reliable machines begin with reliable evidence. The objective is not simply to detect a signal—it is to understand what it means for the asset and what action is justified.

  1. 01
    Acquire

    Collect data that represents the machine and its operating state.

  2. 02
    Diagnose

    Test possible causes against multiple forms of evidence.

  3. 03
    Decide

    Translate findings into a clear, proportionate action.

  4. 04
    Verify

    Confirm that the action produced the expected outcome.
