The Microphone
Software & Data Integrity
Applications
Predictive maintenance and condition monitoring
Rotating equipment (motors, pumps, bearings, gearboxes, compressors), reciprocating machinery, valves and beyond. Each MPK801 supplies the calibrated signal your ML model needs to identify degradation before failure. One sensor per asset, one inference stream.
Process, noise and vibration monitoring
Classification, tagging and detection of acoustic events in fixed industrial installations.
Lab-to-field ML pipelines
Every MPK801 is calibrated to the same reference. Train and deploy on identical hardware, with no domain shift between prototype and production.
