DIL 502 Expedis® Serie

Dilatometry (DIL) is a precise analytical technique that measures dimensional changes in materials as a function of temperature and/or time. It provides critical information on key material properties. These measurements are fundamental for both quality assurance and the advancement of materials research.

Inquiry sample measurement

NanoEye – optoelectrical displacement system

In traditional dilatometry, increasing resolution often reduces the measurement range and vice versa. The NanoEye system overcomes this limitation by offering high resolution alongside an unmatched measurement range. It achieves perfect linearity in thermal expansion measurements, surpassing conventional systems.

Functional Principle:

During a test run, if the sample expands, all green components in the graphics move backwards with the help of a linear guide (marked in blue). The optical encoder determines the corresponding length change directly on the appropriate scale.
