What Is Condition Monitoring?

Condition-Based Monitoring (CbM) is the practice of continuously or periodically measuring physical parameters of machines, vibration, temperature, acoustic emission, lubricant analysis, and motor current, to assess their health and predict impending failures. Unlike time-based preventive maintenance (which replaces parts on a schedule regardless of condition), CbM intervenes only when measurements indicate actual degradation.

Key Condition Monitoring Technologies

• Vibration analysis, accelerometers detect bearing defect frequencies, imbalance, misalignment, and looseness in rotating equipment (motors, pumps, compressors, fans)
• Thermal imaging (IR), infrared cameras detect hot spots in electrical panels, refractory degradation in furnaces, and lubrication failures in bearings
• Motor current signature analysis (MCSA), analyses motor current waveform for broken rotor bars, bearing degradation, and load variations
• Oil analysis, detects wear particles, water contamination, and oxidation in gearbox and hydraulic oil
• Ultrasound, detects early-stage bearing defects, compressed air leaks, and partial discharge in HV equipment

Condition Monitoring Hardware Requirements

A condition monitoring edge node requires a compact, fanless industrial PC or SBC with:

• High-speed ADC or DAC inputs for vibration sensor data acquisition
• Sufficient processing power for real-time FFT vibration spectrum analysis
• Industrial network connectivity (Ethernet, 4G LTE) for data upload
• Wide temperature and vibration rating for mounting near machinery
