TENSILE TEST:

• Automatic test execution under load/stress control and grips separation control (by using the displacement transducer supplied with the machine) with closed loop PID control
• Simultaneous display of load, stress and specimen elongation
• Possibility to overlap two elongation/stress graphs:
  • one obtained with the included displacement transducer measuring crosshead separation travel
  • one obtained with an optional extensometer (coaxial or universal)
• Graphical test data option showing the load/elongation curve

COMPRESSION TEST:

• Automatic test execution of compression tests with closed loop PID control
• Simultaneous display of load and stress, load/time graph

Hydraulics
