SETSYS Evolution TMA

• SETSYS Evolution TMA : an accurate and robust displacement transducer...

Dilatometric measurement from ambient to 2400°C

The displacement transducer on the SETSYS Evolution TMA models is characterized by its robustness and high accuracy: it can detect dimensions changes as small as 0.01 micron. The transducer on the SETSYS Evolution TMA uses an electromagnetic system allowing automatic control of the force on the sample between 0.01 and 1.5 N. This force can be increased by adding weights (up to 200 grams) on a top plate. Transducer calibration and force control are ensured automatically by the computer. • Controlled-rate dilatometry and TMA As for the other models, the computer automaticallymanages operation of the SETSYS Evolution TMA, especially the force on the sample.

r software determines the transition temperatures, plots the derivative curve (DTMA) and corrects the base line.Specific software provides for accurate measurement of the coefficient of expansion in the materials. A calibration curve in the form of a polynomial introducedinto the computer guarantees the accuracy of the coefficient of expansion measured up to 2400°C.With such software, the SETSYS Evolution TMA canbe used as a dilatometer. The SETSYS Evolution TMAis also particularly suitable for measuring controlled-rate sintering.
