DIL 402 Expedis® Supreme HT up to 2800°C
- Two graphite furnaces (final temperature 2400°C and 2800°C) for measuring the thermal expansion of metals, alloys and ceramics in various industries or for special research projects
- High-performance pyrometer for optical measurement of sample temperature from room temperature
- special safety system for monitoring the cooling water and purge gas flow during the entire measurement
- Separation of sample and furnace chamber by a protective tube for the use of different atmospheres
- AutoVac system (optional) for evacuating and refilling the sample chamber
NanoEye - A New Dimension in Measuring Range and Accuracy
A drive applies a controlled force and adjusts the push rod in line with the variable sample length.
The elastic force sensor records the contact force.
An optical encoder measures the initial length of the sample and the associated change in length.
The green components (see adjacent diagram) move backwards with the aid of a linear guide (blue marking) when a sample expands in length. The optical encoder measures the corresponding change in length directly on the scale.
Method
The Method for Determination of Dimensional Changes
Dilatometry is a measurement technique for quantitatively determining the thermal change in length or volume of a material as a function of temperature. It makes it possible to determine the linear or volumetric coefficient of thermal expansion, which is a measure of the expansion of a material when heated. This method is used in materials science, metallurgy, ceramics and polymer research to analyze the thermal properties of materials.

Software
Proteus® - Best Practice for Measurement and Evaluation
The unique Proteus® 7 dilatometer software offers everything a user could ever want and need: It runs smoothly, provides reliable results, and it is fast and efficient. It provides a large range of functions, but – at the same time – offers a clearly-arranged user interface. Additionally, it is intuitive and thus easy to learn. But ... that’s not all. There are some more options inside which impress even the most experienced operators – particularly the Density Determination, the patented c-DTA and the new, innovative Identify software features.
Density Determination
This program add-on allows determination of the density change of samples with varying consistency, i.e., solids, viscous materials such as pastes, liquids or melts as well as the volumetric expansion of isotropic materials.
c-DTA
The c-DTA signal gives the opportunity for simultaneous analysis of length changes and endothermal/exothermal effects. It can also be used for temperature calibration.
Identify
The unparalleled Identify, for the identification and interpretation of DIL measurements includes several NETZSCH libraries with hundreds of entries from the ceramic, inorganic, metal, alloy, and polymer or organic fields. Additionally, user-specific libraries can be created. They can be shared with other users within a computer network.
Identify allows the identification of unknown samples from the absolute values, the slope or the shape of a measured curve. This will also open up the opportunity to compare known samples against a variety of other samples, enabling one to make a statement about material quality. Finally, all measurements can be stored in the extensive database and are always available for identification or quality comparison.
