Unsaturated Soil Testing Shearbox with 4 Channel Data Logger


Unsaturated Soil Testing Shearbox with 4 Channel Data Logger

The VJ Tech Unsaturated Soil Testing Shearbox is used to carry out unsaturated shear tests on soil samples up to 75mm (2.95") (square or round) in a sealed sample chamber. The microprocessor based system incorporates a stepper motor drive for horizontal load, a large graphical display, a touch sensitive keypad and forward/reverse travel limit switches. The pneumatic loading concept is utilised for applying the vertical load to the sample (compressed air supply required). When testing, suction is maintained using a Pneumatic APC at the top of the sample and a Hydraulic APC at the base. Built in data acquisition automates the testing by recording the horizontal and vertical loads and displacements. The Unsaturated Shearbox is bench mounted, designed for harsh lab environments and is of rugged construction.
