Extremely stiff, four-column load frame tensioned without any play Measurement accuracy class 1 according to DIN EN 7500-1 in the specified measuring range. This testing machine combination is a space-saving unit consisting of compression and flexural testing machine which is suitable for compressive and bending strength tests of gypsum, mortar and cement samples, as well as light and aerated concrete. In the basic configuration, the framework is designed for force-controlled tests, whereby the force value is determined via strain gauges.
Optionally a position measuring system can be installed on the compression or bending side. The massive steel frame is extremely stiff. The hydraulic cylinders are made from solid material. The end position is detected by an inductive sensor. The compression side is enclosed by four columns. The bending side is designed as an open C frame. On both side is a simple insertion of different test fixture, inserts and devices possible.
- Solid and stiff 4-column frame
- Large test chamber protection made of transparent polycarbonate
- Long piston stroke of 60mm with optimized test chamber height of 210mm for a wide range of applications
- Force value detection via precise force transducers (DMS based)
- Various fixed test inserts or devices can be adapt into a machine to test according a large number of standards (ASTM / EN / BS etc.)
- DOLI EDCi Control electronics fully-automatic test procedures suitable for force, displacement or deformation controlled tests with predefined loading speeds
- Automatic break detection and free adjustable test end conditions
- Readout and export of measurement data
Safety
The test frame with a control cabinet fulfills all requirements according to DIN EN ISO 7500-1. The complete machine is delivered with an EC declaration of conformity and an operating Instructions according to the Machinery Directive 2006/42 / EG. A large area of the testing machine is equipped with an impact-resistant, transparent test room protection made of polycarbonate. The position of the protective door is monitored by an inductive sensor. When the door is open, the hydraulic unit is depressurized.
Control cabinet
Control cabinet with main switch incl. under-voltage release and emergency stop switch, as well as a “Schuko” plug on the front panel.
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
Measuring and control electronics
As universal digital measuring and control electronics for testing machines, a Doli EDCi20 controller is used. It is installed in the control cabinet and can optionally be operated with a remote control. The control electronics enables a fully automatic test execution with given load speeds for force-controlled tests (position and strain controlled tests optional).With sensitive and adjustable break detection, the failure of the sample is detected early. Communication to the PC: Ethernet socket / USB 2.0 Remote maintenance via TeamViewer function(PC required).
