Refined SPM method saves money at Hallsta Paper Mill
Originally published in "Svensk Papperstidning" #4 2010.
Since April, 2009, Hallsta Paper Mill in Roslagen, Sweden has been engaged in a successful project together with SPM Instrument, where bearing condition has been measured on four twin wire presses using the SPM®HD measuring technique.
Successful solution to the challenge of low RPM bearing monitoring
Originally published in "Uptime Magazine" Feb/Mar 2011.
Low RPM applications have been notoriously difficult to monitor with traditional vibration- based techniques. The energy involved at RPMs below 50 is very low, making it a difficult task to extract meaningful information from the measured signal.
