The Four Production Killers: The primary culprits behind continuous operation failures are rolling element bearings, gearboxes, poor lubrication, and pump cavitation.The Spectral Blind Spot: Standard FFT spectrums often drown out the high-frequency, non-sinusoidal signals generated by machinery impacting and friction, causing early-stage faults to go unnoticed.The Sampling Rate Secret: To accurately capture these defects, sensors require an exceptionally high sampling rate. Without it, reported fault amplitudes can drop by up to 95%, leading to sudden, unpredicted failures.Smart Vendor Evaluation: When selecting wireless condition monitoring sensors, maintenance teams must explicitly ask suppliers for the maximum frequency range, the maximum input amplitude range, and the exact sampling rate to ensure the devices are capable of catching these critical faults.
