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.
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.

Firmware
- Electronic control unit “Cyber-plus Evolution” with Touch-Screen colour display, that runs like a standard PC based on Windows operating system for the management and analysis of the data,
test results, graphs.
- The Touch-Screen icon interface allows an easy set up of the parameters and immediate execution of the test.
- The machine can be connected to a PC for remote test execution through suitable Software; the machine can in any case perform the tests without any external PC, because of the “Cyber-Plus”
grants performances like a PC.
- Direct connection to Intranet (connection to a LAN network) and Internet to establish a remote communication and receive an immediate diagnostic analysis from technicians, or for
updates of the software.
- Unlimited memory storage with: 2 USB ports, 1 SD card slot.
- RJ45 network connection
- Possibility to select different languages.
