Shock pulse monitoring
SPM is an abbreviation for the Shock Pulse Method, which is a patented technique for using signals from rolling element bearings as the basis for efficient condition monitoring of machines. Instant evaluation of bearing condition is given in an easily understood green-yellow-red color scheme.
The Shock Pulse Method, originally invented in 1969, has been further developed and broadened and is now a worldwide-accepted philosophy for condition monitoring of rolling bearings and machine maintenance. Outperforming traditional vibration measurement techniques on many applications, the SPM HD method is unrivaled in its capacity to measure from below 1 RPM upwards. The perfect companion to vibration analysis, SPM HD can be used successfully on all types of machinery with rolling element bearings.
