The Pulsed Mechanical Analyzer (PMA)
Dynamic Material Characterization Under Real-World Loading Conditions
The Pulsed Mechanical Analyzer (PMA) is a unique testing system designed for the dynamic characterization of elastomer materials under realistic pulsed loading conditions. It accurately determines the complex modulus of elasticity and the loss factor (tan δ) in the frequency range from 100 Hz to 1 kHz.
By measuring at high strain levels within milliseconds, the PMA provides material data that closely reflects real operating conditions—offering valuable insights for the design and optimization of dynamically loaded elastomer components.

Dynamic Testing for Real-World Applications
Conventional material tests often provide only limited information about a material's behavior under actual operating conditions. The Pulsed Mechanical Analyzer has been specifically developed to evaluate elastomers under short-duration, high-speed pulsed loads, closely simulating the stresses experienced in many real applications.
By determining both the complex modulus of elasticity and the loss factor, the PMA delivers reliable material data for the development, optimization, and validation of dynamically loaded rubber and elastomer components.
A New Era of Material Characterization
The Future Has a Pulse.
The PMA extends the capabilities of the traditional rebound resilience tester with powerful analytical functions, creating an entirely new approach to material characterization.
Its specially engineered mechanical design minimizes friction and external influences, enabling highly accurate and repeatable measurements under realistic loading conditions.
Material properties that were previously difficult or impossible to quantify can now be measured quickly, reliably, and with exceptional precision.
Fully Automated Testing
Save Time. Eliminate Errors.
At the push of a button, the PMA performs a completely automated measurement sequence.
- Automatic specimen alignment
- Elimination of operator influence
- Reduced measurement errors
- Excellent repeatability
- Fast and efficient testing
The system determines both the complex modulus of elasticity and the loss factor without manual intervention, ensuring consistent and reproducible results.
Temperature-Dependent Material Analysis
The PMA enables temperature-dependent measurements without the need for complex temperature control systems.
Pre-cooled specimens can be tested directly after storage in a standard laboratory freezer, allowing measurements down to -50 °C.
An integrated temperature sensor automatically records the specimen temperature at every measurement point. Between measurements, the temperature is continuously monitored, with freely adjustable measurement intervals.
This allows precise evaluation of material properties across a wide temperature range.
Determining the Glass Transition Temperature Under Dynamic Loading
One of the PMA's unique capabilities is the determination of the glass transition temperature (Tg) under pulsed mechanical loading.
This provides a much more realistic assessment of the low-temperature performance of elastomer components than conventional testing methods.
The resulting data supports the reliable design of components subjected to dynamic loads in demanding applications.
Ideal for Quality Assurance
The PMA combines fast testing with exceptional ease of use and outstanding reproducibility.
Its automated workflow makes it ideally suited for routine quality control in production environments.
Material properties can be evaluated efficiently, documented consistently, and monitored over time to ensure stable product quality and early detection of material deviations.
