The magnitude is then compared with prestabilished limits. It gives vibration measurement by using true RMS velocity. It is based on vibration class of 

22/08/  · The shock pulse method was invented in the late 1960s. In rolling element bearings, there is a phenomenon where electric waves, or elastic waves, or shock pulses, or impact signals, are generated. The amplitude of these impacts is determined by three different parameters. The first parameter, the mechanical bearing condition, is represented by

These shocks 'ring' the SPM transducer which outputs electric pulses proportional to the shock magnitude. Unlike vibration transducers, the shock pulse 

SPM Shock pulse measurement, LR/HR. TD-214. SPM SpectrumTM. TD-218. ISO 2372 vibration monitoring. TD-225. ISO 10816 vibration monitoring with spectrum TD- 

A vibration shock test inputs a sharp transfer of energy into a mechanical system to test its capability to withstand some source of transient vibration. The shock pulse it uses excites a range of frequencies in a short period and dampens quickly. The pulse is either a classical shock pulse or a transient representation of a recorded event.

Special transducers for shock pulses and vibration assure accurate measurements. On measuring points that are unaccessible during normal operation, the.

19/07/  · By Chief Engineer Mohit Sanguri July 19, Guidelines. Shock Pulse Monitoring also known as SPM is a patented technique of predictive maintenance by measuring vibration

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. Even bearing damage can be detected through vibration analysis. A bearing produces a group of peaks in the vibration spectrum, caused by the rolling elements

Difference between shock pulse and vibration The shock pulse meters measure the shock signal on a decibel scale, at two levels. A micro processor evaluates the signal. Shock

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.

Our vibration and bearing shock pulse analysis services measure vibration and shock pulses of assets via predictive maintenance to determine their condition and operating life. We use high quality sensors to measure velocity, displacement and acceleration. The recorded readings are measured against standard vibrations that have been achieved
