Key features

  • The high precision loading system effectively avoids the overloading of the measuring force, and at the same time greatly improves the loading speed.
  • The force selection and hardness scale selection are coupled.
  • Automatic loading and unloading, keeping time .
  • The frame structure is strong and rigid.
  • Correction of test values of cylindrical and spherical specimen.
  • High speed step control, test speed is extremely fast.
  • All Dwell time during the test cycle can adjusted.
  • Automatic closed-loop sensor loading.
  • The curve of test process is displayed, which can display the material characteristics intuitively, which is convenient for observation and learning.

Description

The measurement system uses high-precision displacement sensor with a hardness value resolution of 0.1 HR for accurate hardness results. The load system uses high-precision force value sensor and central controller to form a closed-loop loop to achieve full microsecond level tracking and control of the booster process. Gi-1504 adopted the international advanced closed-loop sensor control technology, to achieve full automatic control and hardness testing process.
