Vibration Monitoring

  Measuring vibration displacement, velocity, or acceleration using transducers like accelerometers and velosometers.

Lubricant Analysis

  Analyzing oil condition and its ability to lubricate according to design specifications (viscosity, acidity, etc.).

  Analyzing oil chemical composition to ensure additives are present in correct concentration (corrosion inhibitors).

  Testing lubrication circuit integrity by looking for contaminants such as water and silicon (Karl Fischer Water Test etc.).

Wear Particle Analysis

  Machine health monitoring and wear life quantification by examining wear particles inside the lubricant (ICP Spectroscopy etc.).

Bearing Temperature Analysis

  Monitoring temperature of the bearings using an infrared thermometer or other thermo-graphic imaging technology.

Performance Monitoring

  Monitoring and trending of process performance parameters such a pressure, temperature, and flow rates to optimize equipment reliability.

  Conceptually similar to “Operating Dynamics Analysis”.

Ultrasonic Noise Detection/Ultrasonic Analysis

  Monitoring and trending ultrasound waves emanating at a frequency over 20 kHz (outside of human hearing rage). Small, lightweight hand-held

ultrasonic detectors can be used for this type of analysis.

Infrared Thermography

  Monitoring thermal profile of equipment using IR cameras.

NDT Thickness Testing

  Using ultrasonic thickness testing (UTT) techniques to access loss of thickness due to metal loss.

Visual Inspection

  Visually checking machine components to ensure that equipment is running safely.

Insulation Resistance Testing

  Detecting insulation failures resulting from excessive heat/cold, vibration, and aging wear (e.g. spot reading tests can be conducted by using a meg-

ohmmeter across the insulation windings  – a test voltage can then be applied for a fixed time duration).

Motor Current Signature Analysis (MCSA)

  Current signature analysis is non-intrusive method for detecting equipment health problems in motor driven rotating equipment.

  Concept  – An Electric motor running mechanical equipment senses load fluctuations within that equipment and converts them into electric current

signatures that can be monitored using MCSA.

Motor Circuit Analysis (MCA)

  Motor circuit health monitoring through electrical testing (using: Ammeter, Meg-Ohmmeter, Volt Ohm Meter, LRC bridge, Oscilloscope etc.)

Polarization Index (PI)

  PI ratio is a measure of the insulation resistance of the motor - taken at different points in time.

  PI ratio can be used to monitor the health of the insulation system and power circuit of the motor.

Electrical Monitoring

  Electrical power quality monitoring/ voltage quality monitoring.

  Energy monitoring & power metering (voltage/current harmonic distortion, kWh usage, kVA, kVAR, voltage, and current).

  Identification of power factor correction related problems.

  Harmonic voltage and current monitoring (prevents overheated equipment, breaker trips etc.).

Crack Growth Monitoring

  Fatigue crack growth propagation monitoring using smart sensors (ultrasonic, image analysis, piezoelectric wafer active sensors etc.).
