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.
This instrument is LabV®️-primed
LabV®️ takes the data from your analytical instrument: It automatically imports all measurement data into a central and secure database solution, the LabV®️ software. This allows you to visualize the data in LabV®️ and to make them searchable. Your data will now be accessible from anywhere. Moreover you have the possibility to generate reports.
