The difference between Low noise and Non-Low noise accelerometer cables. It is important to use the correct cable when using accelerometers. A charge output accelerometer must be used with a…
When performing experimental modal testing of a structure or component using impact (or ping) testing, it is important to consider and verify the validity of any results. A modal analysis…
Mass loading is the phenomenon whereby the mass of the Accelerometer alters the natural frequency of the test subject The video below demonstrates the phenomenon of mass loading and the…
Condition Monitoring Group Ltd (CMG) are pleased to announce the acquisition of DJB Instruments Ltd based in Mildenhall near Cambridge in the UK. DJB will join Prosig, Helitune, Beran Instruments,…
A vital question to be asked before performing hammer testing is - how do I support the testing object? What fixing mechanism to use? Or technically, what are the desired…
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…
The analysis of dynamic engine vibration and the accurate measurement of angular vibration is a non-trivial task, as a more in-depth analysis of boundary conditions reveals. Tools for engine vibration…
Using Source Contribution Analysis (SCA) and Structural Animation (STA) in the DATS software for the analysis of complex structural dynamics This post uses Source Contribution Analysis (SCA) techniques and a…
We have scoured LinkedIn, Twitter and the rest of the Internet to find these cool acoustics links. And since two of them are themselves lists of 10 you're actually getting…
Semia has been a long standing partner with Helitune, one of the CMG companies, and has distributed Helitune products for the last 20 years to the French market. Semia’s specialises…
HVAC (Heat Ventilation Air Conditioning) units are devices used in various applications, such as cars, buildings, aircraft etc. They facilitate the transport and conditioning (heating, cooling, changing of humidity) of…
Download as PDF The National Satellite Test Facility (NSTF) is a new facility in the United Kingdom for the environmental testing of complete satellites and large sub-assemblies. To be operated…
Every year Prosig provide a prize for the best student project at both the University of Portsmouth and the University of Southampton. We are pleased to announce that this year's Prosig Engineering…
Sometimes it doesn't hurt to revisit some of the basic building blocks that form the foundation of what we do. And so we have gathered together a few of our…
Here's our latest collection of noise, vibration & acoustics stories from all corners of the internet. We hope you enjoy them. Leave us a comment. Architectural Acoustics via 99% Invisible…
This post covers how to upsample and downsample data and the possible pitfalls of this process. Before we cover the technical details let us first explain what we mean by upsample…
When analyzing rotating shafts some terms are often confused. This post will attempt to explain the differences. So, what are vibration, torsional vibration and twist? What is Vibration? We measure at…
We've been carefully tracking acoustics related tweets on Twitter and present here a few of the highlights. We do this sort of thing so that you don't have to. Don't…
Richard O'Sullivan is a respected engineer who has worked throughout the world on noise & vibration measurement solutions in automotive, aerospace and beyond. Hear about some of the problems he…
You will be able to meet Prosig and some of our top bloggers at Testing Expo USA 2016 in Novi on 25th, 26th & 27th October 2016. Come along and…
Nyquist theory is generally understood, but this understanding usually relates to time sampling and the conversion to the frequency domain. Rotational order analysis and the effect of the Nyquist frequency…
