DDS-5A/DDS-5C

It is designed to determine the shearing strength of the soil. It adopts transverse processing control drive system and it can not only receive commands through keyboard input, but also be controlled by computer. The recovery rate is delayed to the initial position, providing a convenient way for the shear box to return when restarting a new test or continuing a residual shear test.

FEATURES
   -USB or Ethernet interface for computer control;
   -Integrated LCD display for standalone control, 240*128 LCD screen to show
   -horizontal normal displacement, shear rate, shearing and cyclic shearing rate, etc;
   -Test setup and control facilities;
   -On-board data logging with large data storage on internal u disk (option);
   -Data export via USB link for manipulation within excel;
   -High speed arm processor;
   -High speed sensor data conversion;
   -Built-in live data table and graphs;
   -Built-in auto protection for sensor limits;
   -Non-volatile memory for sensitive data.
   -Fast forward and backward to initial position.
