On show for the first time in the UK at this year’s MAINTEC industrial maintenance and asset management exhibition, the new Machine Condition Advisor (MCA) from SKF, the knowledge engineering company, is an easy-to-use, ergonomically designed, handheld device designed to simplify machine maintenance and prevent costly failures.
Putting the benefits of machine monitoring within reach of any maintenance and operations personnel, the SKF Machine Condition Advisor simultaneously measures vibration signals and temperature to quickly and accurately assess the condition of essential rotating equipment such as pumps, fans, motors, compressors, cranes and conveyors.
Although small enough to fit in the pocket or clip to a work-belt, the SKF MCA features powerful signal processing and advanced technology that leverages decades of SKF’s machine design and monitoring experience, making the device ideal for novice and expert users alike.
Users simply turn the unit on, then press the sensor tip against the part of the machine (usually the bearing) to be measured. Once the readings - displayed on an integral bright backlit LCD - stabilise, the user simply presses a button to ‘hold’ the values, which can then be read and recorded.
The SKF MCA measures velocity vibration signals from the machine and automatically compares them to pre-programmed ISO guidelines, while at the same time applying the industry-proven SKF Enveloped Acceleration technique to compare readings with established bearing vibration guidelines. If measurements exceed these guidelines, the unit’s display shows an ‘Alert’ or ‘Danger’ alarm to indicate potential bearing damage.
Simultaneous with the vibration measurement, the MCA’s infrared temperature sensor also checks bearing temperatures for abnormal heat loads that could indicate lubrication problems.
Powered by an environmentally-friendly, rechargeable Lithium ion battery, the MCA measures vibration signals from 10 to 1000Hz and temperatures from –20ºC to 200ºC. Displays can be switched between metric or English units and the rugged unit is rated IP 54 for use in harsh operating environments.
An optional external vibration sensor fitted with a magnet is also available for use in tight spaces or hard-to-reach surfaces.
“The SKF Machine Condition Advisor is a good fit,” says Phil Burge, Marketing Manager at SKF (U.K.) Limited, “whether a facility is just beginning a predictive maintenance programme or wants to supplement their existing condition monitoring programme. New users can have increased confidence because their readings are automatically compared to established standards or backed up by experienced analysts using SKF data analysers for further analysis.”
