Validate Designs for Shock and Vibration
Mechanical engineers validate designs using shock and vibration tests because, in the real world, products get dropped—and it’s good to know which components pop off of a PCB first. Whether it’s testing a custom vibration sensor or an antivibration feature, shaking a device under test (DUT) in a controlled manner requires large, expensive test fixtures and precision measurements. To get the data they need, mechanical engineers must:
- Rigidly mount the test DUT to a shaker table
- Connect accelerometers to the DUT and shaker table
- Provide excitation to power IEPE accelerometers
- Acquire data at a rate that meets test-frequency requirements
Expandable 8-Channel Accelerometer and Microphone Data Acquisition System
- FlexLogger™ application software for data logging manages sensor configuration, real-time data visualization, export to .csv files, and channel alarms, all without programming.
- cDAQ-9174 chassis holds up to four C Series modules and connects to a PC or laptop over USB. (Ethernet chassis are available.)
- Two NI-9234 sound and vibration input modules for eight input channels that sample at 51.2 kS/s/ch.
- Two open slots for future expansion or higher channel-count systems.
For Smaller Channel-Count Systems, Consider a Measurement Bundle
USB sound and vibration measurement bundles combine a sound and vibration measurement module with a single-slot, USB-powered CompactDAQ chassis for a rugged, portable measurement system at an entry-level price. Combine this bundle with FlexLogger no-code software for quick tests, or program with your preferred development software using drivers for LabVIEW, Python, C/C++, C#, and VB.NET.

Expandable High-Speed Data Acquisition
The accelerometer data acquisition system combines CompactDAQ hardware and FlexLoggerTM software to simplify vibration measurements. See how the vibration template for FlexLogger helps take a simple RMS measurement on a blender.
“FlexLogger software makes it easier to troubleshoot and verify that the raw data from different sensors are correct before I start my test. This helps shorten test development by saving time typically wasted on redoing configurations.”
—Andy Tarman, CNH Industrial
