Equipped with suitable devices, Unitronic tester performs compression, flexural, splitting tensile and direct tensile tests, with automatic load or displacement/deformation control, within the limits of its max. 50 kN capacity for compression/flexural and 25 kN for tensile.
The load is applied by a mechanical jack that is driven by a stepper motor and controlled by an internal microprocessor on a high precision control board.
Stroke electric end switches are applied to the load piston to save the machine from accidental handlings.
The crosshead foresees couplings to fix the different test devices.
The stress is measured by an electric load cell and the displacement control is achieved directly by the high technology electronic board incorporated into the machine within a variable speed range up
to 51 mm/min to cover the Marshall test.
Real time display of time, load, deformation, displacement and graph simultaneously is allowed thanks to the latest generation control board.
