technical features:
by using suitable devices, unitronic tester, within the limits of its max. 200 kn capacity for compression/flexural and 50 kn for tensile, 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.
