This unique instrument based on ultrasonic resonance allows:

– 10cycle testing in 14 hours (compared to 39 days at 300Hz)
– 1010 cycle testing in 6 days (compared to 365 days at 300Hz)

USF-2000A Ultrasonic Fatigue Testing System test cycle per hour graph
  • 20kHz ± 500kHz test frequency
       109 cycle tests in 14 hours (39 days at 300Hz)
       1010 cycle tests in 6 days (365 days at 300Hz)
  • Stress Range: 100MPa to 1,200MPa
       1000MPa steels may be tested
  • ±50 µm displacement at end surface of horn
  • Recreates fatigue failure appearance from micro-defects and inclusions.
  • Resonance technique reduces power consumption compared to traditional fatigue tests.
  • Small tabletop design 
  • Air-cooled, no oil or cooling water required. 
  • Mean stress load option is available.
