Digital Automatic Direct / Residual Shear Machine

This microprocessor based advanced model, is driven by a high-resolution stepper motor with epicyclical no backlash reduction gearbox.
It incorporates a pneumatic closed loop control system for the automatic application of normal load by a high performance pressure regulator, therefore eliminating the need for manual application of dead weights.
This system can also perform different types of automatic shear tests since it is possible, to control the different parameters measured during, the test: for example the constant volume shear test, where the height of the sample is kept constant during the shear stage.
The machine is supplied with shear box adaptor, load cell, linear transducer for horizontal and vertical displacement.
The shear box assemblies are not included and have to be selected and ordered separately.
The machine also requires an air supply, 10-bar max. pressure, 50 lmin capacity.
