Machine condition advisor

Machine monitoring, made simple

SKF Machine Condition Advisor CMAS 100-SL
SKF Machine Condition Advisor CMAS 100-SL

Now both novice users and experts can easily, quickly, and accurately check the condition of rotating equipment throughout your facility. Equipping your maintenance and operations personnel with this rugged, ergonomic and easy-to-use instrument can provide early warning of potential machine problems before a costly failure occurs.

Features

  • Quick and easy to set up and use, measurements are shown on a bright display viewable in low light to direct sunlight. Free on-line training is also available.
  • Lightweight, compact, and ergonomically designed, the SKF Machine Condition Advisor fits neatly at the belt line, in a pocket or a tool kit. Exceptionally durable, the unit is rated IP 54 for use in industrial environments.
  • Alert and Danger prompts provide increased diagnostic confidence.
  • Measuring velocity, enveloped acceleration and temperature simultaneously saves time.
  • Efficient, economical and environmentally friendly, the rechargeable SKF Machine Condition Advisor operates 10 hours on a single charge.
  • Flexible enough to work with standard 100 mV/g constant current accelerometers, an optional external sensor can be used for hard to reach locations and for more repeatable and accurate measurement results.
  • Features English, French, German, Portuguese, Spanish and Swedish for user convenience.

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
  • Temperature in Celsius or Fahrenheit
  • Acceleration enveloping readings in gE
