WAW series Servo-controlled PC analysing Electronic-Hydraulic Universal Testing Machine

WAW series microcomputer-controlled electronic-hydraulic servo universal testing machine is not only suitable for tension, compression, bending conventional tests of metal and non-metal material, but also for low frequency fatigue test of the material and structure. WAW series is a scientific and testing instrument specialized in industrial & mining field, science and investigation department, quality control department, university and college, etc.

Main Function Feature:

  • Hydraulic loading, high precision pressure sensor, high precision displacement sensor, microcomputer procession, digital display.
  • Automatic measuring range switch
  • Constant rate stress control, constant rate strain control, constant rate piston stroke control and loading force long-time-keeping control, etc. are available through three close-cycle rate controlling function with stress, strain and displacement.
  • impact-free shift between constant rate stress control, constant rate strain control
  • Instant display of test curves as load-displacement, load-time, displacement-time, stress-strain.
  • Automatic hydraulic clamping with reliable and none-sliding holding.
  • Hydraulic and electronic overload protection. Piston and beam limit position protection.
  • Automatically adjusting of load, transmutation and displacement according to the standard.
  • Test result can be printed and stored.
  • Low frequency function as square wave, sine wave, triangle wave or trapezoidal wave is extensional.
  • DOLI-Germany all-digital servo control system is optional to perfect and enhance the testing function.
  • Meeting the technical items of Standard GB/T 228-2010 “Metallic Materials – Tensile Testing at Ambient Temperature
