About Digital Shear Apparatus

Digital Shear Apparatus

Digital Direct/ Residual/ Shear Apparatus

Used to determine the resistance to shearing of all types of soil specimens both consolidated and drained, undisturbed or remoulded samples.

The machine can accommodate specimens dia. 60, 100 mm, and square 60x60, 100x100 mm.

The apparatus is equipped with a control closed loop motor with epicycloid reducers.

At the beginning of each test, the machine performs an automatic and complete internal check, a position reset with the elimination of all possible positioning errors and all pauses.

The input of all the test patterns is achieved by the interaction of the keyboard and the alphanumeric display with self-memory, thus granting infinitesimal resolutions in short times.

All data are input and stored when the machine is in stand-by, without affecting the specimen under test with quick machine setting. Possibility to fix maximum excursion of the shear box, so as to interrupt automatically the test.

It is possible to input a different return speed (residual shear) in relation to the one used for the shear test, thus allowing a quick playback to select the residual shear test, saving a lot of time.

For determining the direct shear strength of soils on specimen size 60mm x 60mm x 25mm
