Digital Controller Direct Residual Shear Box

Standard : ASTM D3080, BS 1377-7, AASHTO T236, NF P094 071-1/2

Shear Testing Machines

This machine is used to perform consolidation & shearing phase of a standard direct shear & residual shear test under automatic speed control. The system consists of a micro stepper motor to apply horizontal shear load to the soil specimen, at user-input shearing rate. The shear force readings are obtained from the proving ring at specified intervals of horizontal displacement shown on the touch screen display. Incorporated with limit sensors to prevent shear box from over-travel at forward or reverse motions. Control panel come with LCD and keypad for manually setting and control, large liquid crystal display and with 16 keys membrane, reciprocating shear capability and times are settable built-in 16 bit Data acquisition and control.
