Vibration Measurements

When it comes to quality assurance, vibration measurements are a key component for predictive maintenance and diagnostic fault testing. Vibration measurements can improve reliability and quality of products, reduce support costs by providing early recognition of product weaknesses, and help consistently meet product specifications and regulations in the manufacturing process. Typical vibration applications use IEPE accelerometers for measurement sensors. Data Translation offers two options for vibration applications:

Portable (DT9837A):

  • Four simultaneous 24-bit IEPE inputs
  • Tachometer and 24-bit D/A, synchronize with analog inputs
  • Expandable

Embedded (DT9841-VIB):

  • Eight IEPE inputs for high-accuracy at up to 800 kS/s
  • Real-time control with embedded 300 MHz DSP
  • Expandable
Application Notes & White Papers
[]Shock Testing Using the DT9836 Module and Measure Foundry
Quanta Laboratories needed a data acquisition system with the ability to measure 24 inputs, each with up to 2000 g of resistance, simultaneously. In addition, they wanted to be able to trigger the start of acquisition using a single-axis accelerometer.
[]Using MATLAB for Vibration Measurements
Vibration measurements are critical in predictive maintenance and diagnostic fault testing applications for quality assurance. Typical vibration applications use IEPE (ICPTM) accelerometers to measure vibration and when coupled with MATLABŪ, a well known interactive software environment for data acquisition and analysis, report generation, and test system development, provide a complete set of tools for acquiring and analyzing vibration measurements.
