Touch Screen Frame for Direct Shear Testing

  • Product Code: SL276-KIT
Touch Screen Frame for Direct Shear Testing
Touch Screen Frame for Direct Shear Testing

It is equipped with an advanced, electromechanical operating device comprising a stepper motor, a precision-made reduction unit and a final worm screw with reduced play.

These devices are designed to obtain linear, micrometrical movements at a constant speed and, independently from force developed, fast reverse drive. 

Continual drive speed in either direction can be varied via the electronic control unit from 0.00001 to 9 mm/minute.

RS232 Interface for PC. Touch screen.

The number of cycles, forward/reverse speeds and displacement for the measurement of residual shear may also be programmed.

Accommodates shear boxes measuring up to 100 x 100 mm.
