DIL 402 Expedis Classic

The dilatometer DIL 402 Expedis Classic offers state-of-the-art dilatometer technology and is designed for sophisticated applications.

Infos / Datasheet

Like all instruments of the DIL Expedis series, the Classic version features the revolutionary NanoEye measuring cell; a new dimension in measuring range and accuracy.

NanoEye – Every Nanometer Counts. 

A New Dimension in Measuring Range and Accuracy

In classical dilatometry, the two parameters measurement range and resolution mostly seem diametrically opposed. If the resolution goes up, the measuring range usually goes down and vice versa. NanoEye, the novel opto-electrical displacement system, features perfect linearity and maximum resolution over a measuring range which was impossible to realize until now.

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.
