Log Load, Pressure, Torque, Force, and Strain Data to Excel

Load, force, pressure, and strain data is core to validating structural design capability and durability. From low-speed load tests to high-speed drop tests looking at rosette gage strain on a printed circuit board, mechanical tests are expensive—and test teams needs confidence in a test system to have confidence in the test data. Key elements of a load, force, and strain test system include:

  • Software tools that minimize configuration, setup, and automation efforts
  • Data formats compatible with popular analysis and reporting tools, including Excel, Python, and MathWorks MATLAB® software
  • A cabling solution to distribute and synchronize instrumentation
  • Quality measurement hardware for data confidence and test repeatability
  • Expandability to add more sensors as you discover structural areas of interest

Expandable Load, Pressure, Force, and Strain 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 with one-cable synchronization are available)
  • NI-9237 4-channel, 50 kS/s/channel strain/bridge input module connects to quarter-, half-, and full-bridge sensors, load cells, and pressure sensors with built-in excitation.
  • The system has two open slots for different measurement modules or to expand to higher-channel-count test systems.
  • See the NI-9235 and NI-9236 strain/bridge input modules for higher channel-count, cost-optimized quarter-bridge measurements.

Solution Advantages

“FlexLogger software is easy to use for real-time data logging. It helps me reduce output time and money to create a data-logging system because you don't have to have a degree to know what's going on.”
