Dead Weight Direct Shear Machine

The dead weight direct shear machine uses a 10:1 beam loading device to control confining pressures.  A load cell with digital readout displays shear force and the analog dial indicators measure vertical shear displacement.  In addition, a stepper motor drive controls the strain rate within 1% and is easily adjustable using digital thumb wheel controls.

Additionally, the unit includes a 2.5″ diameter stainless steel shear ring, porous stones, drainage plates and loading block. The unit also includes a Teflon coated anodized aluminum water chamber.
