TECHNICAL FEATURES:
By using suitable devices, Unitronic tester, within the limits of its max. 50 kN capacity for compression/flexural and 25 kN for tensile (see model S205-05N), performs compression, flexural, splitting
tensile and direct tensile tests, with automatic load or displacement/deformation control.
The load is applied by a mechanical jack that is driven by a motor brushless with closed loop through optic encoder and controlled by a microprocessor. Stroke electric end switches are applied to the
load piston to save the machine from accidental handlings.
The two crossheads foresee couplings to fix the different test devices (see accessories). The stress is measured by an electric load cell; the measurement and the displacement control of the
crosshead is achieved by the electronic device incorporated into the machine.
