Thermomechanical Analyzer (TMA)
Thermal expansion with neglectible load
With the thermomechanical analysis (TMA) the change in sample geometry is measured with additional sample loading via the temperature.
Static tests include: Expansion, penetration, tensile and compression tests as well as 3-point bending.
By applying an oscillating force to the sample, the dynamic mechanical analysis (dynamic TMA) records its frequency and temperature dependence as well as the viscoelastic properties and thus determines the modulus of elasticity and the damping values.
All TMA devices operate in accordance with the following national and international standards (DIN 51 005, ASTM D 3386, ASTM E 831, ASTM D 696, ISO 11359 – Part 1 to 3).
The concept
Both the temperature and the atmosphere can be controlled separately.
An optional mass flow controller for regulating a purge gas is also available.
The vacuum-tight cell enables measurement under defined atmospheres.
This means that samples that are sensitive to oxidation can also be measured perfectly.
Furnace: A range of robust and reliable ovens is available for the TMA Platinum series.
The individual design enables extremely fast heat-up and cool-down times, as well as excellent temperature control over the entire measuring range.
