ASI Digital Direct Shear Testing Machine, ASI-5A

ASI Digital Direct Shear Testing Machine, ASI-5A

Introduction

ASI-5A is used to perform the 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 the user-input shearing rate. The shear force readings are obtained from the proving ring at specified intervals of horizontal displacement shown on the touchscreen display. Incorporated with limit sensors to prevent the shearbox from over-travelling in forward or reverse motions.
