Description

 

The machine consists essentially of a robust two column high stiffness frame (200 kN/mm) with an upper crosshead, which is factory-preset at your desired height, and of a lower mobile bi-directional crosshead adjustable by the user using the dedicated push buttton or via the PC software.

The machine features an advanced closed loop PID control system assuring very fast reaction time and extremely accurate test control, particularly important for critical tests, such as those on FRC and FRP specimens. The stress is measured by a load cell incorporated in the upper crosshead and the displacement by a high-resolution encoder with 0.1 micron resolution.
The machine is fitted with two limit switches working at upper and lower full travel and two additional limit switches adjustable by the client in the desired position, according to the specific accessory in use. A remote push-button is used to quickly position the lower crosshead.
 
The machine is supplied complete with:

  • High specs all-in-one PC 
  • Load cell 250 kN cap. Up to three other cells of lower capacity for tests on low strength materials can be connected (for not simoultaneous use)
  • Adapters to connect main accessories
  • DATAMANAGER Software for compression and flexural tests
