SKF CMAS 100-SL - Handheld Vibration Meter

• Handheld Vibration Meter
• 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.
• 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.

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.

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:

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

Press “Select” or “Browse” button to turn the SKF Machine Condition Advisor “On”.
Press the sensor tip against the point to be measured.
When the readings stabilize, press the “Select” button to hold the reading.
Read and record the measurement values.

Understanding and using guidelines for vibration

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.

How to choose the correct “Alarm Velocity Group” for your machinery

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)

• 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.

Groups 1 and 3

• 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 multi-vane impellers and integrated drivers.
