- SPM launches the revolutionary SPM®HD measuring technique. This digital refinement of the original Shock Pulse Method is applicable on all types of applications and is particularly well suited for low speed machinery.
Condmaster®Nova 2010 was also released, offering many new features. Among them is the Colored Spectrum Overview, a brand new way of presenting historical spectrums and viewing trends and patterns graphically.
- The portable instrument VibChecker hits markets worldwide. Like the popular BearingChecker, this new measuring device is an entry-level instrument for condition monitoring. VibChecker delivers reliable and accurate vibration information in just seconds.
- SPM introduces Intellinova®, an online system for condition monitoring. The system uses well-proven methods and modern technology to ensure highest possible accessibility on critical machinery.
- Leonova™ Infinity, Bearing Checker and SLD transducer released.
- LineLazer, the shaft alignment kit for Leonova™ introduced.
- Another breakthrough in condition monitoring techniques: SPM Spectrum enables the first true and calibrated shock spectrum analysis. Evaluated bearing condition measurement is combined with easy pattern recognition to verify the shock pulse source.
- EVAM® is introduced, confirming the steady efforts of SPM to develop simpler and more efficient evaluation methods.
- Shock pulse measurements and vibration measurements were combined in a first step towards comprehensive condition monitoring. At the same time, SPM developed life cycle analyses for an overall assessment of the economic consequences of condition monitoring.
- After intensive work, we were able to incorporate, in the deepest sense of the word, the lubricating condition of the bearing into the SPM®Method. The second half of the 1980s saw a virtually revolutionary development of the software. Our world and that of our customers became computerized.
- SPM has installed millions of measurement points, and has sold 40 000 units of the portable 43A measuring instrument - a true classic.
- The SPM company was formed. After only a couple of years, we developed the first rules for evaluating the measurement signals that Søhoel succeeded in isolating. Even today, we are devoting major resources to developing these rules, both in the laboratory environment and on the industrial scene.
- Eivind Søhoel, the inventor, patented the shock pulse method which identifies the weak shock pulses from rolling element bearings.
The history of SPM began in the 1960s. At that time, condition monitoring consisted of putting an ear to a wooden rod or screwdriver and listening to the sound of the machine.
If something could be heard, it was usually already too late. A.P. Møller, the Danish ship owner, found out from bitter experience that the cargo pumps of his tankers were breaking down far too often without forewarning. An inventor and an enterprising financier decided to do something about it.
