Model No. :
Brand : Netzch
The High-Force DMA 503 Eplexor Series is a robust testing platform engineered to analyze the viscoelastic properties of materials under significant mechanical loads. By bridging the gap between standard analytical DMA and universal testing machines, it allows for the characterization of large-scale industrial components and high-stiffness materials.

Features
Set for the Future
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 non-stop 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.
Wide Deformation Range at High Resolution
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.
Two Independent Drives for Static and Dynamic Force
Just as with the base DMA 503 Eplexor®, the DMA 503 Eplexor HT instrument operates with two independent drives for static and dynamic force. Application of this principle is the only way of utilizing the entirety of the broad range of force when carrying out DMA measurements.
Broadest Temperature Range
By combining the high-temperature furnace up to 1500°C with a cooled low-temperature furnace, a range from -160°C to 1500°C can be covered in one DMA instrument. The furnaces are easily interchangeable by the user.
Rigid Design
High temperatures place high demands on the flexural strength of the fixture within the hot- temperature zone. The DMA 503 Eplexor HT instrument is equipped with sample holders made of sintered silicon carbide (SSiC), a dense and stiff ceramic that maintains this property even at 1500°C.
Variable Force Range
This one-of-a-kind DMA system offers the ability to install different force sensors to meet individual users’ needs, with a total force range from 10 N to 2500 N. This allows for applications of the best possible conditions in order to optimize results. The force sensors can be changed easily by the operator with a minimum of effort.

Software
The comprehensive DMA 503 Eplexor software is based on Windows operating systems. The extensive software package comprises data and curve analyses, hysteresis representation, master curve calculations, etc. It also includes specific templates for tension, compression or bending tests.
The software features include:
- Frequency sweep of 0.0001 Hz to 100 Hz (optional up to 200 Hz for fatigue)
- Temperature sweep (controlled temperature variation at fixed frequency)
- Time sweep from 1 s to 107 s
- Correlated temperature and frequency sweep at isothermal steps
- Correlated dynamic and static strain amplitude sweeps; equidistantly or logarithmically subdivided
- Evaluation of complex modulus (E*, G*), storage modulus (E’, G’), loss modulus (E’’, G’’) damping factor (t and δ) by temperature sweeps, strain and force sweeps, time sweeps, glass transition temperature, and optional creep, relaxation, fatigue, energy loss, hysteresis, Payne/Mullins effect analysis
- Prediction of the rolling resistance of tires (optional)
