The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves 

We offer advanced vibration monitoring techniques for early detection of a wide variety of mechanical fault conditions such as unbalance, misalignment, resonance, looseness, and faulty gears or bearings on all types of rotating machinery. Machine vibration monitoring is the most widespread method to determine the health of rotating equipment.

Shock pulse monitoring 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.

These devices include two embedded accelerometers to provide a wide dynamic range to capture low amplitude

Accelerometers measure vibration acceleration, shock pulse (roller bearing condition) and pump cavitation Also available in compact size, for low-speed machines and as combi sensors for vibration and temperature Patented tandem-piezo technology eliminates the disadvantages of conventional sensors

The shock pulse method (SPM) has been widely used as a quantitative method for bearing condition monitoring. However, the shock value 

Vibration and temperature readings provide vital data about the health of your machines. Uncover these insights with the SKF Pulse. Combining an easy-to-use sensor with a free mobile app, you can quickly and easily identify machine condition without the need for training or diagnostic expertise How to get started

The pressure wave quickly dampens out. The pressure wave that first goes through the materials (before it starts to vibrate) is called a “shock pulse”. While 

Shock and vibration logger with integrated 3-axis digital accelerometer and lithium-polymer battery. A shock data logger or vibration data logger is a measurement instrument that is capable of autonomously recording shocks or vibrations over a defined period of time. Digital data is usually in the form of acceleration and time.

In recent decades, the shock pulse method has been developed to detect faults in the early stage of rolling element bearings degradation. In this paper, the 

In this paper, the vibration analysis methods and shock pulse method (SPM) are compared in order to detect the unhealthy condition as well as fault type in
