Hydraulic system The powerful hydraulic unit with 20L oil tank incl. all necessary safety, control and directional valves according to DIN 4413. It generates a maximum system pressure of 350 bar and a volume flow of 1.2L / min. A fine 3µm pressure filter in the pressure line is filtering the hydraulic oil and protecting the system components. Incl. filter pollution, oil level and temperature switch(70°C). The hydraulic unit is inside of the control cabinet and is thereby particularly low noise < 66 dB (A). A high-quality servo valve for pressure or volume flow control enables the most precise force and position control (closed-loop control).
Measuring and control electronics Doli EDCi20 controller as universal digital measuring and control electronics for testing machines. Installed in control cabinet and can be operated remote. The control electronics allows fully automatic test execution with given loading speeds for force controlled tests (position and strain controlled tests optional). Sensitive and adjustable break detection, the sample breaks early. Communication to PC: Ethernet socket / USB 2.0 Remote maintenance via TeamViewer function (PC required).
