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.
