Spot the change. Decide what to check.

Compare each recording with a stable reference. Try two examples to see why the pattern matters as much as the average.

Public test-rig recordings from UCI. Client telemetry and hardware are kept separate.

Data source, reference method and limits

UCI hydraulic systems dataset · Helwig, Pignanelli & Schütze · CC BY 4.0. Display aggregation modifies the original sampling resolution.

Nine separate stable cycles form the phase-aligned mean and sample-standard-deviation reference. Original reference rows: 1788, 1789, 1790, 1791, 1792, 1793, 1794, 1795, 1796. The healthy displayed cycle is held out.

Comparison band: reference mean ± max(3 × sample standard deviation, channel-specific minimum tolerance). For TS1: 0.25 °C. These are illustrative screening parameters, not manufacturer alarm limits.

Recorded component labels describe the experiment. The functional illustration is not a verified mounting diagram. This benchmark is separate from confidential client hardware and telemetry.

Case review

Investigating

Recorded experiment condition

The experiment labels this cycle at 20% cooler condition; the other component labels are held at the healthy reference settings.

What the evidence supports

Temperature describes thermal state. The controlled cooler label supplies experiment context; this trace does not identify a particular physical cooler defect.

60 of 60 seconds fall outside the phase-aligned band. Longest run: 60s.

Possible mechanism

Cooling removes heat from the hydraulic oil. A lower cooling condition can shift temperature and efficiency over repeated load cycles.

Temperature differences support a cooling-performance concern. This trace does not establish which physical cooler fault was responsible.

Next checks to request

Check cooler airflow, fan operation, dirty heat-transfer surfaces, fluid flow, and thermostat or bypass behaviour. Those are investigation hypotheses, not causes proven by this recording.

Reviewer notes

Notes and requested checks are required. Review records a human assessment; it does not confirm a machine fault or a completed maintenance action.
