DIL L74 Optical Dilatometer
Optical Dilatometer with Camera
Description
On point
The Optical Dilatometer DIL L74 OD is a specialized instrument designed to meet the rigorous requirements of industries such as glass, ceramics, metals, and energy. It incorporates a high-resolution CCD camera that allows for real-time visual analysis of sample expansion. This visual analysis can be viewed as single frames or video sequences, offering valuable insights into how materials behave during thermal processes.
One significant advantage of this method is that it exerts no mechanical force on the sample. This feature is especially beneficial when working with soft samples or materials that may melt during the measurement. Without contact pressure, the results obtained are not distorted, providing accurate and reliable data.
The LINSEIS Evaluation Software, integrated into the system, offers various correction and analysis features, enhancing the utility of the instrument. The horizontal design of the Optical Dilatometer DIL L74 OD allows for the analysis of even the most demanding applications in materials research and testing.
The Optical Dilatometer DIL L74 OD comes equipped with a special solid-liquid adapter that is designed for performing expansion and volume measurements on a wide range of materials, including solids, liquids, and solid-liquid phase transitions. This versatility allows researchers to investigate various types of materials under different conditions, providing valuable insights into their thermal behavior.
In addition to the solid-liquid adapter, the system offers special sample holders specifically designed for measuring rigid foils. These sample holders are essential in applications where pushrod forces, common in classical dilatometers, can introduce measurement errors. By eliminating these forces, the Optical Dilatometer DIL L74 OD ensures the accuracy and reliability of the data acquired during the experiments.
Measurement principle
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.
