Dynamic Mechanical Analyser

Linear Servo Motor

Capable of producing high forces and velocities, the Linear Servo Motor ensures accuracy and reliability throughout the testing process. When operated, the Linear Servo Motor will begin to apply force to the sample under testing, and the reaction force of the sample is measured on the load cell. The test results are sent through to our new Labline software, which interprets the data and displays the results graphically. Our Labline software can also calculate the viscoelastic properties of the sample including hysteresis effects, complex modulus and tan delta.

Service Flexibility

This instrument has been designed keeping our customers testing needs in mind. With minimal maintenance required for the DMA, operator productivity levels are maximised. Should a service and calibration be necessary, the integrated high quality parts are easy to access and remove, making it a simple and convenient process.

Linear Encoder

A high performance Linear Encoder is supplied as part of the Linear Servo Motor, providing precise and reliable position feedback and communication data.

Environment Cabinet

An optional temperature test chamber can be incorporated to give control, stability and flexibility of temperature during testing.

Safety

This instrument can be relied upon for a simple and safe operation and has an emergency stop feature integrated into the design to protect users, whilst conforming to international safety standards.

Low Noise Operation

When in use, this Dynamic Mechanical Analyser will produce minimal mechanical noise enabling a productive test environment for the operators.

Static Stress/Strain

In this mode, stress or strain can either be constant or applied at a uniform rate. Results include Young’s Modulus, Hookean stiffness, elastic limit, material strength and distortion at break.

Dynamic Stress/Strain

At constant frequency, material response is monitored as stress amplitude increases. For each cycle, the complex stiffness, complex modulus and complex viscosity can be calculated. Can also be used to identify the Linear Viscoelastic Range.

Multi-Frequency

At constant frequency, material response is monitored as stress amplitude increases. For each cycle, the complex stiffness, complex modulus and complex viscosity can be calculated. Can also be used to identify the Linear Viscoelastic Range.

Transient Testing

For creep testing, stress is held constant and deformation is measured over time. For stress relaxation, the stress required to hold a constant deformation is measured over time. This mode is used to measure the long-term effects of loading and the ability to return to original shape.

Time-Temperature Scans

With the optional temperature control unit, material response as a function of temperature can be measured. Thermal transitions, rate of cure and operating ranges can all be determined. Samples can also undergo accelerated ageing during testing.
