SDTA Signal

Unsurpassed Temperature Accuracy

The TMA/SDTA 2+ is the only instrument on the market that measures the sample temperature very close to the sample in all operating modes. This enables temperature adjustment to be carried out using reference substances (e.g. the melting points of pure metals) or through a change in length.

DLTMA mode

The DLTMA mode allows you to study the elastic behavior of samples.

Unique temperature calibration

The METTLER TOLEDO TMA models have two thermocouples: One mea- sures the furnace temperature and controls the program temperature. The other is located next to the sample and measures the sample temperature.

The various deformation modes

Dilatometric mode (A): This is the mode most commonly used in ther- momechanical analysis. The expansion coefficient is determined as a function of temperature. A typical feature of this mode is that the probe exerts only a very small force on the sample.

Compression mode (A): In this mode, the sample is subjected to a large force.

Penetration mode (B): The purpose of a measurement in the penetra- tion mode is to determine the softening point of a sample. This is usu- ally performed using the ball-point probe.

Tension mode (C): The fiber or film accessory is used to perform mea- surements in tension. This allows you to determine changes in length due to shrinkage or expansion.

3-point bending mode (D): This mode is ideal for studying the elastici- ty of stiff samples such as fiber-reinforced polymers.

Swelling (E): Many substances swell when they come into contact with liquids. The resulting change in volume or length can be mea- sured using the swelling accessory.

Volume expansion (F): Liquids expand just like solids. A new acces- sory enables you to measure volume changes of liquids.
