MULTISPEED digital automatic universal tester for displacement controlled tests

suitable for CBR, Marshall, indirect tensile, unconfined compression and many other displacement controlled tests

EN 12697-34 | ASTM D1559 | ASTM D5581 | AASHTO T245 | EN 12697-12 | EN 12697-23 | AASHTO T193 | ASTM D6927

34-V1072 MULTISPEED tester

Main Features

The firmware provide the digital speed control and a number of important test functions as follows:
  • Closed loop speed control
  • CBR and MARSHALL test speed can be selected by default.
  • Other testing speeds (Custom) between 0.2 and 51 mm/min, can be easily set.
  • Selection of maximum platen displacement. 
  • The automatic stop of the machine avoids machine and specimen overloading, thus assuring operator safety.
  • Rapid approach function, to reduce the testing time.
  • Rapid platen return to speed up the platen base return at the end of the test.
  • Speed calibration function by firmware. The test speed is originally factory calibrated using a polynomial interpolation. A test point is provided to verify  the speed with a standard tachometer.
  • Emergency stop button as required  by the CE prescriptions.
  • tecnical specifications
    • Scroll the table
      • Max. capacity:  50 kN
      • Test speed range, infinitely variable: 0.2 to 51 mm/min
      • Power: DC motor 750 W
      • Horizontal clearance (distance between columns): 270 mm
      • Max. vertical daylight (without accessories): 730 mm
      • Platen travel: 100 mm
      • Overall dimensions (lxwxh): 392 x 495 x 1213
      • Net weight approx.: 65 kg 
      • Alphanumeric display 2x16 characters
