Shock pulse method (SPM) is a technique for using signals from rotating rolling bearings as the basis for efficient condition monitoring of machines. From the innovation of the method in 1969 it has been further developed and broadened and is a worldwide accepted philosophy for condition monitoring of rolling bearings and machine maintenance.

In bearing condition monitoring, management systems not only monitor bear vibration date, but also bear pulse data by a shock pulse method (SPM) [2]. In these cases, the observation indicators are

Pulse pressure is the difference between the upper and lower numbers of your blood pressure. Pulse pressure tends to increase as you get older, and this number can also be an indicator of health problems before you develop symptoms. If you want to monitor your blood pressure on your own, blood pressure cuffs are available in most pharmacies

A shock pulse transducer contains a reference mass (m) and responds with a dampened oscillation when hit by a shock wave. Attached to the reference mass is a 

2003/11/02 · SPM stands for shock pulse monitoring. The term “shock pulse” describes what is produced when a ridge or asperity from one surface contacts a ridge or asperity of another surface when the lubricant film, designed to separate those surfaces, is lost. The pulse is a high-frequency signal that is collected with a sensor tuned to measure noise

12/16 · Shock Pulse Phase. When two pieces of metal, in motion, contact each other two interrelated yet distinct processes occur. On initial impact a shock or pressure wave develops

11/22 · Take this opportunity to learn about the Shock Pulse Method directly from the source. This method was invented by SPM Instrument in Sweden in 1969 and has been widely

Condition based maintenance on board, vibration & shock pulse monitoring. ANDERS HEDLUND. VIKTOR FORSLIN. Department of Shipping and Marine Technology.

Shock Pulse Monitoring also known as SPM is a patented technique of predictive maintenance by measuring vibration and shock pulses of bearing in motors and to identify their condition and operating life before the next overhaul procedure.

The SPM meter measures the shock pulses per second and then lowers its threshold so that two amplitude levels are discovered, first the decibel carpet value of
