In vibration analysis, a signal is an electric voltage or current which is an analog of the vibration being measured. The signal is usually meant to be the desired part of the quantity, and the accompanying undesired part is called noise. The signal to noise ratio is an important parameter in any measurement system.

As these shocks 'ring' the shock pulse transducer, it outputs electric pulses proportional to the shock magnitude. Unlike vibration transducers, the shock pulse 

Vibration analysis is done to analyze the realiability and health of the machines and their components by looking for anomalies and monitoring change from the vibration signature of a

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

However there is a difference between vibration analysis and Shock Pulse Measurement. Credits: vibrationsound.webs.com When two metal surfaces contact each other while in motion, an impact occurs and a shock wave develops, which travels through the metal. The shock wave is in ultrasonic range and is around 36 KHz.

Time waveform: A time waveform is acceleration vs. · Fast Fourier Transform (FFT): FFT is defined as an algorithm used to calculate a spectrum from a time 

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

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.

Shock Pulse Measurement (Vibration Analysis) - KSB Web-Shop. The signal processed in the transducer is transformed within the measuring circuit in such a way that the result is an indirect impact speed. mining systems bronze parts boyd crusher jaw crusher jaw plates wet overflow ball mill ing bearing ball mill jaw crusher for sale.

VIBRATION MEASUREMENT. Sometimes though, mechanical vibration performs a useful job. For example, we generate vibration intentionally in component feeders, concrete compactors, ultrasonic cleaning baths, rock drills, and pile drivers. Vibration testing machines are used extensively to impart a controlled level of vibration energy to products

various industries. Spike Energy measurement can provide early indications of machinery faults and is a very useful tool in vibration analysis. In addition to the traditional Spike Energy overall measurement, Spike Energy spectrum and Spike Energy time waveform were also developed and used in diagnostic analysis in recent years.
