Centrifugal compressor monitoring, built on the data you already collect.
TruPrognostics AI diagnoses stage degradation, bearing wear, and seal leaks on centrifugal compressors before they cascade. Process-domain analytics from your historian on day one. Frequency-domain analytics with a single vibration sensor.
Four high-impact fault modes from our compressor coverage matrix.
Tracked against the expected operating map.
Polytropic efficiency degrades as internal clearances open up and seals wear. TruPrognostics AI tracks per-stage efficiency against operating point and produces a remaining useful life forecast at every tier.
Detected before mechanical damage.
One of the most common precursors to centrifugal compressor failure. Catchable in the process domain at Base; resolved with frequency-domain precision at Plus and Premium. Remaining useful life forecast at every tier.
Diagnosed from process data alone.
Worn or damaged seals let gas recirculate from the high-pressure side to the low-pressure side, reducing effective stage work. The signature shows up as a specific pattern of efficiency loss on the affected stage.
A precursor to bearing failure, diagnosed precisely.
Sub-synchronous vibration patterns characteristic of fluid-film bearings approaching their stability limit. Diagnosed with frequency-domain analytics on raw vibration waveforms at the Plus and Premium tiers.
Process data first. Waveform where it earns it.
Centrifugal compressors are well suited to process-domain analytics. The relationships between pressures, temperatures, flows, and stage performance are well understood, and your historian already has the data.
TruPrognostics AI starts there. Detected anomalies are diagnosed against a library of fault-specific models, each calibrated to the physics of how the failure mode shows up in process variables. Where the data permits, the system also produces a remaining useful life forecast.
For mechanical and bearing-specific faults that don't surface cleanly in process data, a single high-frequency vibration sensor unlocks the frequency-domain analytics. One sensor, substantial diagnostic uplift.

PI / historian process data. Stage efficiency, compression ratios, hydraulic performance. Catches efficiency loss, seal degradation patterns, and broad bearing decline.
Add one high-frequency vibration sensor on the bearing housing. Resolves bearing wear, oil whirl and whip, and mechanical signatures to fault-specific diagnoses.
Multiple high-frequency sensors. Maximum diagnostic precision on the most critical assets in your fleet.
