Multiple methods and corresponding apparatuses for efficient and reliable defect diagnosis in components of mechanical systems, are described. According to one aspect, multi-scale enveloping-order spectrogram is used to diagnose, or detect, defects in a moving component of a mechanical system. According to another aspect, defect identification and diagnosis in a motor is performed based on spectral characteristics of motor current envelope. According to yet another aspect, a logic rule model, employing classification of features associated with single- or multi-sensor data, is employed for diagnosis of defects in components of mechanical systems.

Methods and apparatuses for defect diagnosis in a mechanical system

A device for a drill rig comprising a ruggedized housing and a sensor contained in the ruggedized housing, the sensor adapted to measure at least one condition of a lubrication oil of an equipment on the drill rig. In an embodiment, the ruggedized housing can have a Class I, Division 1 & 2 standard rating according to UL1203 & FM3600(3615).
