Hands-on condition monitoring is essential for maximum bearing service life and machine health. To help ensure long bearing service life, it is important to determine the condition of machinery and bearings while in operation. Good predictive maintenance will help reduce machine downtime and decrease overall maintenance costs.
What is the purpose of condition monitoring?
Condition monitoring is a key component of managing the maintenance and operability activities in a modern operating and maintenance organization for nuclear and sophisticated power plants.In essence, condition monitoring aids in maintaining the efficiency and safety of plant operations. The corresponding decision contexts are represented as process models in order to create a framework for comprehending issues and solutions linked to the use of condition monitoring data in strategic and operational maintenance decision-making.The following condition monitoring products are the essential monitoring tools that no industrial manufacturing plant should be without:
Thermometers are essential for accurate temperature measurement of general equipment.Since the dawn of the industrial age, operators and technicians know that abnormal temperatures often indicate that something is wrong with the machine.Thermometers can help find and then measure these hotspots, allowing for further analysis.SKF has a variety of thermometers and thermocouple probes to complement your condition monitoring or predictive maintenance program by assessing and reporting on temperature.
Contact and infrared thermometers
Dual laser infrared and contact thermometers
K-type thermocouple probes
A thermal camera enables you to detect hot spots before they cause troubleUsing an SKF Thermal Camera is a proactive way to help you detect problems before they occur, increasing uptime and improving safety. They allow you to be able to visualize potential problems, invisible to the naked eye, by presenting a picture of the heat distribution of an asset.The thermal image, presented on a large LCD screen, shows you where the temperature is either too hot or too cold allowing you to pinpoint potential problems fast.

Multiple measurements with a single device
The SKF Machine Condition Advisor provides an overall “velocity” vibration reading that measures vibration signals from the machine and automatically compares them to pre-programmed International Organization for Standardization (ISO) guidelines.An “Alert” or “Danger” alarm displays when measurements exceed those guidelines. Simultaneously an “enveloped acceleration” measurement is taken and compared to established bearing vibration guidelines to verify conformity or indicate potential bearing damage.The SKF Machine Condition Advisor also measures temperature using an infrared sensor to indicate uncharacteristic heat.
Accuracy, flexibility and confidence
When performing measurements, the SKF Machine Condition Advisor’s acceleration sensor input signal is processed to produce two different measurements for each POINT on the machinery – overall velocity and enveloped acceleration.At the same time, the SKF Machine Condition Advisor’s non-contact infrared sensor measures the surface temperature of the measurement location and simultaneously displays all three measurement values.Depending on the SKF Machine Condition Advisor’s System setting, the front-panel LCD simultaneously displays:
Metric or Imperial units
Velocity in mm/s RMS or in./s derived Peak
The temperature in Celsius or Fahrenheit
Acceleration enveloping readings in gE

Static vibration sensor
The SKF Machine Condition Indicator is an economical vibration sensor and indicator for monitoring non-critical machines. It is ideal for machinery with constant operating conditions not previously monitored in plants.The device can be compared to the "check engine" light in a car. What the "check engine" light does for the car, the SKF Machine Condition Indicator does for industrial machinery.Internal sensors measure velocity, enveloped acceleration (bearing or gear impulsive vibration) and machine surface temperature. The included magnetic read-key is used to activate the SKF Machine Condition Indicator, change operating modes, set vibration baselines and acknowledge alarms. The unit features three LEDs to indicate the machine and bearing condition. Once the unit is illuminated, it alerts the predictive maintenance technician to do a root cause analysis on the machine.In addition, it features a barcode with a serial number for machine identification purposes and easy incorporation into an Operator Driven Reliability (ODR) program, maintenance routes or scheduled check-ups.
Electrical discharge detector
Detect electrical discharges in electric motor bearingsThe SKF Electrical Discharge Detector Pen (EDD Pen) is a simple to use hand-held instrument for detecting electrical discharges in electric motor bearings.Electrical discharges are a result of motor shaft voltages discharging to earth through the bearing, causing electrical erosion, lubricant degradation and ultimately bearing failure. Electric motors are more vulnerable to suffering electrical erosion in bearings when controlled by a Variable Frequency Drive.When incorporated into a predictive maintenance programme, the EDD Pen can help detect bearings more susceptible to failure, and significantly prevent unplanned machine downtime.
A unique remote solution allows operation at a distance from the motors. This helps protect the user from touching machinery in motion
No special training required
Capable of detecting electrical discharges on a time base of 10 seconds, 30 seconds or indefinite
LED Backlit screen, allows use in dark environments
