ITM Provides Global Solutions

 

ITM provides software development, structural and mechanical testing services, industrial monitoring, strain gauging, and data analysis solutions to clients on five continents.  ITM is located in Milford, OH, but our software and hardware packages are used throughout the world.  For the past 18 years ITM has traveled to where our specialized services are needed.  Whether it is performing tests at 16,500 ft in the Andes Mountains or on oil rigs in the Gulf Coast, installing strain gauges at extreme temperatures, or monitoring systems in the US or on the other side of the world, ITM understands the challenges of working in tough environments and will ensure your projects are successful whether home or abroad.

If you need tests performed or monitoring systems developed anywhere in the world, contact Ryan Welker (ryan.welker@itestsystem.com or 1.844.837.8797 x702).

iTestSystem Tip: Impact Hammer Setup

While iTestSystem is designed to collect data from specific sensor types like strain, voltage, current, and accel; custom signal types such as pressure, displacement, and force can also be configured by utilizing the Custom Scale functionality during the channel creation process.

For example, manufacturers often need to measure the amount of force required to install a component using a calibrated impact hammer.  Since iTestSystem does not have a specific channel type for impact hammers, we must create one using a similar channel type.  The channel type most similar to an impact hammer is the accelerometer channel.1

Example Impact Hammer: PCB Model 086D20

To configure a piezoelectric impact hammer in iTestSystem, first create an accelerometer channel.  An accelerometer channel will supply the impact hammer with IEPE constant current.  From the accelerometer configuration window, change the Units to “From Custom Scale”, set the sensitivity to 1, and set the sensitivity units to Volt\g.  Next, set the custom scale: scaled units to lbs, lbf, or N, Prescaled Units to g, and in the slope field, input the lbs\Volt value from the hammer’s calibration sheet.  After entering these settings, be sure to hit the Test button to verify your signal and save the settings after verification.

Notes

  1. Most impact hammers are piezoelectric and require IEPE constant current excitation.  Several iTestSystem compatible National Instruments (NI) cDAQ input modules (NI-9230, NI-9231, NI-9232, and NI-9234) can supply IEPE excitation for an impact hammer.  These modules are typically used for piezoelectric accelerometer inputs.
