SPM HD can be used to monitor applications in the 0.1 - 20,000 RPM range. Throughout their lifetime, bearings generate shocks int he interface between the loaded rolling element and the raceway. These shocks 'ring' the SPM transducer which outputs electric pulses proportional to the shock magnitude. Unlike vibration transducers, the shock pulse

Today condition monitoring is practiced extensivelythroughout the world including, India. Sensitivity of the SPM technique to bearing condition.

The LR/HR method was developed from the original Shock Pulse Method for condition diagnosis of rolling element bearings. It allows the precision analysis of oil film condition in the interface between the outer and inner races and contains calculation models for finding the optimal lubricant.

The Shock Pulse Method (SPM) is the front line technique the Hallsta paper mill chose to quickly manage input from its 800 rolls, with 4000 machines and 1 6,000 measurement points. With 8 inspectors, they need a quick method to know whether bearings need to be greased or not, or that damage is present and needs to be monitored more frequently.

SPM is a well-established technique. Initially, SPM was launched to enable the technician to cost-effectively track bearing condition. The tool proved effective as a method to assess general lubrication requirements as well. Shock Pulse Basic Principle of Operation. SPM stands for shock pulse monitoring.

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 used ever since. Learn about the basics of the method as well as the latest inventions that brought Shock Pulse into the HD era. Takeaways: – What are the advantages of Shock

The Shock Pulse meter then calculates an index number and applies it to the raw Shock Pulse signal. The result is a normalized Shock Pulse reading that can be 

Condition monitoring (colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), Ultrasound is used in the Shock Pulse Method of condition monitoring. Performance analysis, where the physical efficiency, performance, or condition is found by comparing actual parameters against an

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 used ever

Shock pulse method is a widely used technique for condition monitoring of rolling bearing. However, it may cause erroneous diagnosis in the presence of 

The shock pulse method (SPM) has been widely used as a quantitative method for bearing condition monitoring. However, the shock value indicating the bearing condition may be mistakenly estimated by direct demodulation in the SPM. To overcome this deficiency, a new approach based on improved redundant lifting scheme (IRLS) is proposed.
