SKF Machine Condition Advisor CMAS 100-SL Machine monitoring, made simple
SKF Machine Condition Advisor simultaneously measures vibration signals and temperature to indicate machine health or bearing damage.
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 at SKF @ptitude Exchange. • 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 noncontact 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: • • • •
Units in Metric or English Velocity in mm/s RMS or IPS derived Peak Temperature in Celsius or Fahrenheit Acceleration enveloping readings in gE
Quick and easy – first time and every time 1 Press “Select” or “Browse” button to turn the SKF Machine Condition Advisor “On”. 2 Press the sensor tip against the point to be measured. 3 When the readings stabilize, press the “Select” button to hold the reading. 4 Read and record the measurement values.

Understanding and using guidelines for vibration
Options are: G2 and 4R (default)
The SKF Machine Condition Advisor provides a means to evaluate machine health based on ISO 10816-3 and to evaluate the bearings according to general guidelines developed from a statistical analysis of existing databases.
Alert: 2,8 mm/s (0.16 ips) Danger: 4,5 mm/s (0.25 ips)
How to choose the correct “Alarm Velocity Group” for your machinery
G1 and 3R
The Alarm Velocity Group (G2&4 or G1&3) determines the instrument’s “overall vibration” alarm limits. Therefore, select the Group that best describes the general size, type, and speed of the machinery being measured. Note that these machine group classifications are set forth in ISO 10816-3, which rates overall velocity vibration levels for standardized machinery classifications. Groups 2 and 4 (default) ISO Group 2 and 4 classifications define the following type of machinery: • Medium-sized machines and electrical machines with a shaft height between 160 and 315 mm (6.3 and 12.4 in.). • These machines are normally equipped with rolling element bearings, but may use sleeve bearings, and operate at speeds above 600 r/min. • These machines include pumps with multi-vane impellers and integrated drivers.
Extension sensor kit Model CMAC 105-K G2 and 4F Alert: 4,5 mm/s (0.25 ips) Danger: 7,1 mm/s (0.39 ips)
Alert: 4,5 mm/s (0.25 ips) Danger: 7,1 mm/s (0.39 ips)
• Large machinery and electrical machines with a shaft height greater than 315 mm (12.4 in.). • These machines are generally equipped with sleeve bearings, but may use rolling element bearings. These machines include pumps with multivane impellers and integrated drivers. Rigid or Flexible foundation? An additional setting allows the specification (when defining the overall alarm levels) of measurements taken from machinery with Rigid (default) or Flexible foundations.
The Extension sensor kit CMAC 105-K contains an accelerometer with integral cable (CMAC 104) and magnet (CMAC 109) with mounting stud. This kit is needed to take measurements from hard-to-reach places and for more repeatable and accurate measurement results.
G1 and 3F Alert: 7,1 mm/s (0.39 ips) Danger: 11,0 mm/s (0.61 ips) How to choose the correct “Enveloped Acceleration Classification” for your machinery The Enveloped Acceleration Classification (CL1, CL2, or CL3) you specify determines the instrument’s “bearing vibration” alarm levels. Therefore, the Enveloped Acceleration Classification that best describes the general size and speed of the bearings being measured should be selected. Options are:
Accelerometer • 100 mV/g sensitivity • Small size case • 0,5 to 15 000 Hz frequency response (±3 dB) • Waterproof
CL1 Bearings with a bearing bore diameter between 200 and 500 mm (7.9 and 19.7 in.) and a shaft speed below 500 r/min. Alert: 1 gE Danger: 2 gE
Integral cable (1,5 m standard) • Connector to SKF Machine Condition Advisor CMAS 100-SL • Various cable lengths available Magnet, Model CMAC 109
Groups 1 and 3 ISO Group 1 and 3 classifications define the following type of machinery:

Alert: 4 gE Danger: 10 gE Note: As with all commonly published severity guidelines, the above provides target thresholds for new, refurbished and recently maintained equipment. In addition, if both lower limits of the guideline are used (for example in CL2, a 50 mm bearing bore diameter at 500 r/min), the applicable alarm values maybe lower. Note that bearing bore diameter is equal to shaft height.
