Vibration Data Integration Analysis

Simplify Acceleration Conversions with iTestSystem’s Integration Analysis Tool 

Like many features in iTestSystem, the Integration Analysis tool was created because customers requested it. After all, who doesn’t like features that make the math easier?

In this blog, a new series by ITM, we’ll share some details about Integration Analysis, one of the features within TestView Plus, the project based data viewing function within iTestSystem. 

For engineers who are gathering vibration data, it makes perfect sense to have a simple way to convert acceleration into units of velocity or units of displacement since those are the most common specs.

Enter the Integration Analysis function. Simply open TestView Plus, drop down the “Analysis” tab and select “Integration.” Once there, adjust the settings to either “Single Integration” for velocity or “Double Integration” for displacement. In a couple of additional clicks, you can also specify your desired units and adjust the high cutoff frequency to filter low frequency data. 

The next time you are gathering data using accelerometers, let iTestSystem simplify all those conversions with Integration Analysis.

Weed Out Unwanted Data with Filter Analysis

For engineers, the faster one can weed out the noise, the more efficiently one can deliver actual solutions.

The software architects at Integrated Test & Measurement have added new plugin technology to  iTestSystem, their proprietary engineering measurement software platform, to enhance the user experience by allowing users to analyze data faster by filtering frequencies simply.

In this blog, a new series by ITM, we’ll share some details about one of the features within TestView Plus, the project based data viewing function within iTestSystem.

Once you’ve configured your test using NI MultiDAQ hardware and begun logging strain gauge and accelerometer data, it is time to do an FFT (fast Fourier transform) Analysis to further analyze your signals for frequency information to learn how the system you are testing is actually vibrating.

As part of that process, the Filter Analysis plugin allows users to filter out unwanted frequencies — say anything over 100 Hz — which only requires checking a simple low-pass filter option, a tool embedded right within TestView Plus.

Without leaving TestView Plus, you can simply choose which signals you wish to view, configure a few options on the screen and click the FFT button to output helpful data files for your report or plot directly within TestView Plus to begin isolating specific vibration issues.

Stay tuned for additional iTestSystem features.

Reduce File Size with Resample Analysis

Going Small Can Yield Big Results Thanks to Resample Analysis Feature 

While it may seem counterintuitive to those used to gathering massive data files to solve complex engineering challenges, certain situations actually require gathering smaller files if you want to run a successful test. 

For example, certain tests require gathering data on remote machinery over multiple months. In that instance, the onboard hard drive that’s storing the data will simply run out of space if you are gathering data at a high sample rate.  

The team at Integrated Test and Measurement anticipated such needs. In this blog, a new series by ITM, we’ll share some details about Resample Analysis, one of the features within TestView Plus, the project based data viewing function within iTestSystem. 

Though simple, the Resample Analysis function allows you to perform a powerful function — to greatly reduce file sizes while maintaining an accurate picture of the information gathered. With one click, raw files that were saving at 20 MB and larger are reduced to less than 1 MB, yet your engineers will still be able to capture an accurate picture of the test. 

The process is easy. Open TestView Plus, add a channel, plot some data and click the Resample feature, just remember to also use the Filtering feature to avoid aliasing your data. Though you are sacrificing frequency content, you are gaining data storage, and the data will still tell you the big picture of what’s happening.

Use FFT Analysis in iTestSystem to Pinpoint Vibration Issues

Simplifying Process for FFT Analysis using iTestSystem to Pinpoint Vibration Issues 

The software engineers at Integrate Test & Measurement are constantly looking for ways to enhance and simplify your experience using iTestSystem, their proprietary engineering measurement software platform.

In this blog, a new series by ITM, we’ll share some details about one of the features within TestView Plus, the project based data viewing function within iTestSystem. 

Are you one who tires of gathering vibration data in one tool then having to port it over to a whole separate tool to analyze the signal data? Thanks to plugin functionality in the latest version of iTestSystem, you can now manage both functions all from the same screen.

Once you’ve configured your test using NI MultiDAQ hardware and begun logging strain gauge and accelerometer data, it is time to do FFT (fast Fourier transform) Analysis to further analyze your signals for frequency information to learn how the system you are testing is actually vibrating.  Without leaving TestView Plus, you can simply choose which signals you wish to view, configure a few options on the screen and click the convenient FFT button to output helpful data files for your report or plot directly within TestView Plus to begin isolating specific vibration issues.

Sort Data Faster Using iTestSystem’s Trigger Analysis

Sort Your Engineering Data Faster Using iTestSystem’s Trigger Analysis Feature

Tired of getting buried in a mountain of engineering data? The team at Integrated Test & Measurement feels your pain, and they have built some relief into their data collection software known as iTestSystem.

In this blog, a new series by ITM, we’ll share details about iTestSystem’s “Trigger Analysis” feature, which is commonly used to help analyze, sort and pass crucial engineering data — think strain and vibration — to those who need it most and just in time.

The Trigger Analysis tool separates a data file in one or many files based on the customized data trigger(s) that have been configured, and that’s a feature that saves engineers countless hours.

Here’s how Trigger Analysis works: 

If you are an engineer attempting to gather data from a piece of machinery, vehicle or complex system, iTestSystem allows you to establish triggering events so that reports are only sent when that event hits a minimum or maximum threshold. For example, if you know a damaging event occurs at a certain threshold, you can easily set iTestSystem to only report information or graphs to you when an accelerometer goes over a maximum level or when an engine passes a set RPM.

In other words, the software is gathering data constantly, but it only sends the data when it matches a specific threshold.  

By configuring Trigger Analysis along with both Notification Services and the Automated Analytics features in iTestSystem, engineers are able to greatly simplify processes that require hunting down system operation outliers or damaging events. These iTestSystem applications allow users to analyze, build, and send sensor level reports only when specific vibration and strain limits are exceeded. In the end, that leads to a massive time savings. Instead of searching through streams of data files, engineers can easily review the report and download relevant data files from deployed systems for further analysis.
