Description The Economy Dilatometer series L76 was developed to be used for CTE measurements in ceramics industries, like Brick and Tile industry, Porcelain industries and industries manufacturing building materials. 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 1600°C with different furnaces. It consists of measurement systems made out of quartz glass (up to 1000°C) and Al2O3 up to 1600°C. The sensor is a highest precision LVDT (linear variable differential transformer). This sensor has an indefinite resolution. The analog signal coming from the LVDT sensor is A / D converted in an especially developed controller / data acquisition PCI card. The PCI card fits into most standard computers using Microsoft ® operating systems. 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

Application example: Porcelain and stoneware industry The picture shows a measurement of a clay sample with a Dilatometer. The sample shows a small change of expansion at 570°C which comes from a Alpha / Beta Phase Transition of the quartz crystal structure. This type of Dilatometer measurement is important for the quality control in the porcelain and stoneware industry. This method will quickly determine the quality of raw materials used for the production of white wares.
