Machine Features

The key machine features of the 25CT BOX C are as follows:

  • Four averaging high resolution auto ranging load cells with accuracies better than +/-0.5% down to 1/1000th of the load cell capacity
  • Automatic recognition and calibration of extensometers and load cell, with instant calibration check facility
  • 800% overload capability of load cells without damage
  • Compact design, giving economy of floor space
  • Complete digital testing system with high precision control and accuracy, includes automated computer control of test methods giving simplicity of operation
  • Crosshead guidance system providing smooth running and precise alignment
  • Precision crosshead control via digital AC servo drive and brushless servo motor providing maintenance free operation and 4,000,000 steps per revolution positional control
  • High speed data collection systems for up to four synchronous channels
  • 6 I/O channels for additional devices such as micrometers, extensometers, balances, callipers, etc.
  • High stiffness loading frames with specialized steel crossheads and rigid extruded support columns with T-slots for accessory mounting
  • Overtravel, overload and impact protection
  • Telescopic covers providing additional protection for ballscrews against testing debris and dust
  • Four high efficiency pre-loaded self clearing ballscrews for quiet, fast testing. Fitted and sealed for life lubricated end bearings.
