The Optical Research Dilatometer DIL L74 OD was developed to meet the demanding applications of the glass, ceramics, metal and energy industry. A high resolution CCD camera enables a visual real time analysis of the sample expansion, either as single frame or as video sequences.
The big advantage of this method is that the sample is not burdened with any force. For soft samples or samples that melt during the measurement, this leads to a result, which is not distorted by the contact pressure.
Several correction and analysis features are incorporated into the LINSEIS Evaluation Software. The unique horizontal design enables most demanding applications.
The special solid-liquid adapter allows expansion / volume measurements of solids, liquids and solid – liquid phase transitions. There is also a special sample holders for measuring rigid foils available, which avoids measurement errors due to pushrod forces like in a classical dilatometer.
- Non contact Expansion measurement
- High resolution CCD camera
- Optical Fleximeter
In an Optical Dilatometer the sample is compared with a reference during the measurement. The result is the difference between the two lines. The field of view has an area of 3.3 x 2.8 mm.
