The Linseis high-pressure dilatometer L75/HP enables completely new applications in thermal analysis. The system can measure expansions (length changes) in the temperature range from RT up to 1100/1400/1800°C and in the pressure range up to 100/150 bar. This device is the world's only available high-pressure dilatometer. A steam generator and camplex gas control system are optional available.
An get even more informations and extend your measeurement, an analysis of the effluent gases can be done by using a QMS or FTIR system at any time. But the coupling is more than only the sum of the separate parts. You can benefit from LINSEIS coupling knowledge and integrated hard- and software concept. For the interpretation of the results, different libraries are available.

Software:
All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a Dilatometer measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.
Applications:
Polymers, Ceramic/Glass/Building Materials, Metals/Alloys, Inorganics
Ceramics, Building Materials and Glass Industry, Automotive / Aviation / Aerospace, Research, Development and Academia, Metals / Alloys Industry, Electronics Industry
The thermal expansion of rock crystal can be easily evaluated with the L75 Dilatometer. The additional DTA feature enables an in depth view of the thermal behavior of the material. The DTA measurement is a mathematical routine based on the sample temperature. Exo- and endothermic effects influence the change of the sample temperature during the dynamic heating or cooling cycle. At app. 575°C the phase transition from takes place. The deviation of the measured temperature from the literature value (574°C) can be used for a temperature calibration.
The linear thermal expansion (delta L) and the CTE of the iron sample under argon atmosphere are evaluated. The heating rate was 5K/min. After 736.3°C (peak temperature of CTE) shrinkage was detected, this is due to a change in the atomic structure, known as the curie-point. The difference of measured and literature result can be attributed to contamination of the sample.
