SKF introduces a multi-featured vibration monitor for both conventional and hazardous environments. The SKF Multilog On-line System DMx combines both protection (to help avoid catastrophic failures) and condition monitoring functionality in a single device, making it ideal for monitoring critical machinery such as gas turbines, generator sets, motors, pumps and compressors in the hydrocarbon processing industry (HPI), power generation industry, and other applications. The DMx already has been installed in HPI sites around the world.

Awarded ATEX, IECEx, and cULus certifications, the DMx monitoring system can be directly installed within a hazardous area, removing or reducing cabling, cabinets and isolation barriers and ultimately saving time and money during installation.

"Until now, field-installed intrinsically safe vibration devices have been confined to simple transmitters that provide only basic machine health information," said Chris James, business area director for SKF Reliability Systems. "The complexity of the vibration measurement has been in conflict with the power restrictions imposed by intrinsic safety. With the DMx we've been able to resolve this conflict and offer a vibration monitoring solution that - for the first time - allows the requirements of critical machinery monitoring, from transducer to dynamic data processing, to be fulfilled by an intrinsically safe device located on the machine skid."

The SKF Multilog DMx system's modular design, distributed architecture and small footprint have cost and installation advantages over traditional 19-in. rack systems, said James, including energy savings due to low power consumption. Features include four dynamic input channels for vibration, axial thrust and dynamic pressure, with two channels for speed/phase measurements. Multiple LEDs provide local indications of module, channel and alarm status and diagnostic data. The device can be connected easily to plant control and information networks by common protocols.

The Multilog DMx functions as an independent monitor or as a complete system connecting to plant-wide fieldbus infrastructure and SKF's asset management tool, "@ptitude Monitoring Suite." SKF Group is a global supplier of products and solutions within the areas of rolling bearings, seals, mechatronics, lubrication systems, and services. Services include technical support, maintenance services, condition monitoring and training.
