High-Force DMA 503 Eplexor® Series up to ± 500 N Dynamic Mechanical Testing Systems Analyzing & Testing

Smart Material Testing s of n 40 year mMore tha p for remiu sis D & R in e ly experienc ic mechanical ana nam quality dy Successful introduction of materials and products onto the market is always preceded by a great deal of testing to determine suitability in day-to-day applications. Temperature, time, frequency, load level and other parameters change the viscoelastic properties of polymers and composites. How are your products influenced by different temperatures or moistures? How do the material properties depend on mechanical loading or different frequencies? What is the lifetime of the material...

Dynamic Mechanical Analysis The Dynamic Mechanical Thermal Analyzer applies forced periodic loads to the sample and analyzes the phase shift between this primary excitation and the material’s response. The response of an ideal elastic system (e.g., spring) on a sinusoidal load at a given frequency is of the same frequency and exactly in phase with the excitation. The situation changes in a real system: A phase shift (δ > 0°) between the primary excitation and response of the same frequency occurs in the case of linear visco-elastic materials (e.g., polymers); see figure 1. Elastic and non-elastic...

MODULAR DESIGN – ALL SET FOR THE FUTURE The DMA 503 Eplexor® series allows for a variety of upgrades – to meet the challenges of tomorrow today!

The DMA 503 Eplexor® series allows for easy upgrading the system with a variety of force sensors and strain extensions as well as furnaces. For nonstop operation, a fully automatic sample changer is available. The different DMA 503 Eplexor® versions are operated without a hydraulic pump system - thus providing energy-efficient operation. Strain is accurately measured by two contactless optical sensors. This allows nanometer resolution throughout the entire range of up to 80 mm static displacement and up to ± 6 mm dynamic amplitude. Just as with the base DMA 503 Eplexor®, the DMA 503 Eplexor®...

Connection to static drive Unique by Virtue of Real-Time Operation and Digital Signal Generator The DMA system allows for real-time operation. The quasi-continuous frequency range with high data acquisition rate allows operation between 0.0001 Hz and 100 Hz. Frequency sweeps with high detection sensitivity are suitable for detecting even weak transitions and can be taken for master curve generation. For fatigue measurements, the maximum frequency can be extended to 200 Hz. The optional digital signal generator for conventional and pulse DMA is a prerequisite for generating excitation signals...

THE PERFECT SAMPLE HOLDER FOR ANY APPLICATION All investigations, characterizations and quality control tests conducted on a given material should be aligned with its intended application. The results obtained via measurements which closely parallel real applications allow for more accurate appraisals of a material’s true performance. A variety of sample holders in standard geometries (e.g., bending, tension) are available, as well as in dedicated user-defined geometries. Immersion systems are also offered, see page 9. Tension for stiff samples Dual cantilever

SIMULATION OF ENVIRONMENTAL INFLUENCES Environmental conditions may cause water uptake and therefore play a decisive role in manufacturing processes and the storage of materials. The DMA 503 Eplexor® in combination with the HYGROMATOR® humidity generator is able to create a humid environment inside the test chamber to reveal the influences of environmental humidity on mechanical properties. HYGROMATOR® – The World's First Climate Chamber for DMA The HYGROMATOR® can adjust humidities from 5% rH to 95% rH in the temperature range between 5°C and 95°C. Measurements can be performed under stepwise...

IMMERSION FOR TESTING SWELLING BEHAVIOR AND OTHER EFFECTS The immersion bath allows for measurements in a liquid such as water or oil in combination with sample holders such as those for 3-point bending tests (picture on the right) or tension tests (picture on the left), in cases where evaporation and decomposition temperature of the solvent or liquid are not an issue.

MEASUREMENTS IN PASSING With the Automatic Sample Changer (ASC), the DMA 503 Eplexor® model becomes a fully automated testing system. These systems provide measurement results with the same or even higher level of reproducibility compared to manual sample changing but may be operated 24/7. The ASC is offered in different configurations for up to 160 samples. Automatic Sample Changer You can select your required samples in tensile, compression, shear or bending. The Automatic Sample Changer (ASC) removes the samples from the magazine and places them into the temperature chamber at analysis position....
