High Channel Count Structural DAQ Systems

At ITM, we understand that our customers do not settle for good enough. When it comes to measuring and capturing data for real-world applications and structural analysis, you cannot compromise, so neither can we. Instead of having to pick and choose the most critical locations to measure, we ensure that you can capture every piece of data you need, simultaneously. Whether that is a single strain bridge, or thousands of strain channels.

On past projects, we have worked with our customers in the manufacturing industry to test the structures of their aerospace, mining, construction and other transportation equipment.  Some of these applications not only needed to collect strain, vibration, voltage, and other signals simultaneously but also required well over a thousand total sensor channels.  Network synchronization technology embedded within the NI cDAQ chassis allow users to account for the sheer number of channels during these structural tests. The true secret to our success in these high-channel jobs has been our iTestSystem software which leverages the cDAQ’s synchronization technology while providing an intuitive data acquisition and sensor configuration and setup.

iTestSystem is far more than just a barebones data collection software. It can be a time saver to our engineers by helping to sort channels, keep various tasks organized, and even provide an easy and quick way to view results with the integrated TestView Plus Application (shown below).

The mining shovel pictured below, which is similar to other equipment that ITM has instrumented in the past, illustrates a distributed data acquisition system for collecting data. Using iTestSystem, we can implement a modified tree synchronization topology to collect data from over 20+ cDAQ chassis simultaneously.  Data can be collected in one giant file containing all sensor channels or saved into separate files based on location.  In past projects, we saved over 1000 channels from strain, acceleration, and voltage sensors into a new file every 10 minutes.  We added the sensor location to the sensor description, including the Boom, Operator Cab, Main Frame and Base. This allowed us to easily sort data both during and after the collection.

Our goal at Integrated Test & Measurement is to provide efficient testing solutions and services to address your company’s needs.  If you need to measure high channel counts, or have questions about our rugged DAQ systems, software, rental equipment or testing services, then please contact ITM by phone or e-mail.

Machine Design Article: Feeding the Next Generation of Product Development

Check out the article “Feeding the Next Generation of Product Development” in Machine Design magazine.  In this article, ITM president Tim Carlier describes how engineers are collecting real-world data to get a true look at how their designs are used in the field, and how to design a better machine.  By utilizing iTestSystem and its automation tools, test engineers can implement unattended field tests that continuously analyze and send data based on specific operating conditions.  Armed with data from these tests, designers can better quantify and predict future performance and develop products that satisfy the complete range of actual customer usage.
