Description
The main application field for the L76 Dilatometer series is the CTE measurement in the Ceramics, Brick, Tile, Porcelain and building materials industry. Furthermore it is widely used for quality control purposes in ceramics and in metal industries.
The instrument covers a wide temperature range from RT up to 1000, 1400 and 1600°C with user exchangeable furnaces. It consists of measurement systems made out of quartz glass (up to 1100°C) and Al2O3 up to 1600°C. The sensor is a highest precision LVDT (linear variable differential transformer). This sensor has an indefinite resolution.
Together with the 32 Bit software package WIN-TA / WIN-DIL, the Dilatometer provides an excellent solution for standard quality control type CTE measurements.
The following physical properties can be measured:
CTE, Linear Thermal Expansion, Alpha Physical, Sintering Temperature, Phase Transformations, Softening Points, Decomposition Temperatures, Glass Transition Temperatures

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.

Glass sample, softening point
The glass sample was measured with the softening-detection feature. In this case, the heating ramp is terminated either if the target temperature set is reached, or if the shrinkage of the sample reaches a given threshold. In the run, the threshold was set to - 100µm - when the change in length measured falls 100µm below the maximum value of the actual heating segment, the heating is terminated and the next (cooling) segment will be processed. So, the softening point can be detected in an easy and safe procedure.
