WP 140.20 Data Acquisition System Show data sheet (pdf file) Print page
Technical Description

  This data aquisition system is an extension for the material tester WP 140. The software processes the measuring values for force and number of turns until the test sample breaks (number of load cycles). The stress-number curve is calculated using these data and displayed in colours on the computer screen. The curves can be saved and printed. A specially designed loading device fitted with strain gauges for force measurement will be supplied.

  When the software is started on a PC (not included), it detects automatically the connected amplifier. The measured values can be transmitted directly to a PC via USB.


Learning Objectives / Experiments

- Performing bending fatigue tests
- Processing, display and saving of data
- Output of stress-number curve (tension over endurance)



* Electronic data acquisition and evaluation of
  bending fatigue tests
