SKF Multilog DMx firmware 7.20 maintenance update 2011-01

The SKF Multilog DMx firmware 7.20 adds the following new functionality to the SKF Multilog DMx system:
  • Acceleration enveloping: With the new 7.20 firmware, acceleration enveloping is available as a selectable measurement property within the existing data acquisition scheme of the SKF Multilog DMx. The SKF Multilog DMx will support SKF filters ENV1, ENV2 and ENV3.
  • Rod-drop measurement support: The gap and the phase reference ("keyphasor") of the crankshaft are measured together. This overall triggered rod-drop has not been available on past SKF products.
  • Data acquisition control: Support for input channel enable or disable and single configuration based channel multiplexing support. The multiplexing support allows sequential heavy load measurements (i.e., ENV3 and wide band acceleration measurements) using flexible measurement time slot definition with respect to measurement duration and number of parallel channels.
    Note: Multiplexing mode will not comply with API 670 protection regulations and shall therefore only be used in Monitoring Mode.

The SKF Multilog DMx firmware 7.20 has the following requirements to activate the new features.
  • SKF Multilog DMx Manager 5.1.1 or higher
  • SKF @ptitude Analyst 5.0 or higher to support acceleration enveloping and rod-drop measurement types
