[An Introduction To Vibration Analysis – Part 5] Welcome to Part 5 of our ongoing introduction to the world of vibration and acoustic measurement and analysis. Here, we look specifically…
[An Introduction To Vibration Analysis – Part 4] Welcome to the fourth part of our ongoing introduction to the world of vibration and acoustic measurement and analysis. In this post,…
[An Introduction To Vibration Analysis - Part 3] Modal analysis is one of the most widely adopted vibration measurement techniques for studying the dynamic behaviour of structures and mechanical components.…
[An Introduction To Vibration Analysis - Part 2] Introduction This post on vibration measurement techniques is the second in our series, introducing vibration analysis. Future posts will continue the exploration…
This article will look at the basic steps needed to measure noise & vibration in rotating machines. We won’t look in great detail at some of the techniques involved – we deal with these elsewhere on the blog. This material is suitable for a newcomer to the field who understands the basic concepts of noise & vibration analysis but has not dealt with rotating machinery before.

The identification of cyclic events in rotational analysis is often key to identifying problems. It is good practice to use a suitable sensor for capturing rotational speed. However, this is…
When using an analogue channel input channel of a P8000, with a tachometer sensor, is it possible to utilise the tachometer processing functions as you would if you were using…
In the DATS Multiplane Balancing Software, there are two options, optimise for ‘Zero imbalance’ or optimise for ‘Specified imbalance’, but what is the objective of these two options?

A long-standing customer brought along his power station turbine test rig so that we could give the P8000 hardware and DATS software a good workout. Here's a video of the…
In this post we will first look at how to process data from rotating machinery. Then we will focus on shaft or gear train twist. Let's look at 3 different…
A method to identify subjectively objectionable disturbances (e.g. piston slap, valve tick,… etc) in internal combustion engines
Picture the scenario; you have captured some noise & vibration data from a rotating machine. Typically, this might be noise in a vehicle cabin, but could have been anything from…
So you've got some noise and/or vibration data from a rotating machine, but no speed information. Surely that means you can't analyse against speed or do any order analysis, right?…
When performing frequency analysis of vibration data for any application the resultant spectrum has both amplitude and phase components, therefore the phase component represents half of the information available and…
In the previous two articles (What Is Resonance? (Part 1) & What Is Resonance (Part 2)) in this series we have looked at how we can identify a resonant frequency.…
There are a number of ways to find the natural frequency (resonance) of a part like an automotive inlet manifold. Here are three different types of popular test techniques. But which one should you use and why?
(more…)This article addresses two basic approaches to analyzing rotating machinery during transient (sweeping rpm) conditions. The first is the traditional method which uses Frequency (FFT) Spectrum analysis at target rpm…
Recently, we decided it was about time we had a new model for testing, training and demonstrations. Specifically, we wanted something that would allow us to test the full capability…
When measuring noise and vibration in rotating machines, especially complex devices like automobile engines, it is very important to fully understand what is being measured and what analyses need to…

Creating a good quality tachometer signal is one of the hardest parts of analyzing rotating machinery. So what happens if we have missing tachometer pulses? The data looked great until we tried to perform some in-depth torsional vibration analysis. And now we no longer have the component or vehicle to retest it. Do we have to scrap the whole test? Was all that time wasted? Not necessarily…
IBERDROLA has launched a renewal plan for the existing condition monitoring systems in their plants in Spain. This plan will be implemented gradually and PROSIG was selected to install their PROTOR Vibration Condition Monitoring System in three IBERDROLA power stations. The contract was awarded to PROSIG in partnership with Aries Ingeniería y Sistemas, who are PROSIG’s representative in Spain.
PROSIG have already successfully commissioned and installed the PROTOR system in the Lada (Asturias, Spain) and the Pasajes (Guipúzcoa, Spain) power plants. The work primarily consists of the supply, installation and signal cabling of the PROTOR systems together with training of the IBERDROLA staff. PROSIG will complete the third installation at the Velilla power plant, located in Palencia, Spain in September 2010.
