Product catalog summary
Overview
The Optical Research Dilatometer L74 is designed for applications in the glass, ceramics, metal, and energy industries. It features a high-resolution CCD camera for real-time visual analysis of sample expansion without applying force, making it ideal for soft or melting samples.

Key Features
  • Non-contact expansion measurement
  • Horizontal design for demanding applications
  • Special adapters for solid-liquid phase transitions and rigid foils

Applications
  • Heating microscopy
  • Optical fleximetry
  • Sessile drop and contact angle measurements
  • Solid-liquid expansion

Industries Served
  • Glass
  • Metal
  • Enamel coatings
  • Ceramics
  • Energy

Technical Specifications
  • Temperature range: -100 to 1600°C
  • Accuracy: up to 1μm
  • Atmosphere: oxidizing, with optional reducing, inert, and vacuum
  • Interface: USB
  • Software: LINSEIS Optical Analysis Software

Functional Principle
The dilatometer measures ash melting behavior under defined temperature ramps, providing automatic evaluation according to DIN 51730. It is suitable for analyzing coal ashes, bio ashes, slags, ceramics, and more.

Comparison with Pushrod Dilatometer
The optical dilatometer offers contact-free measurement, avoiding the force applied in pushrod dilatometers, which can affect sintering processes.

L74 Optical Dilatometer-2

The Optical Research Dilatometer L74 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 LIN-SEIS Evaluation Software. The unique...

Optical Dilatometer Liquid applications The investigation of sintering processes using pushrod dilatometers has The optical dilatometer can also be used to investigate the behavior of one disadvantage: There is always a force in z-direction that can cause melts and liquids. The contact angle as well as sphere and half sphere a certain sinter direction. The optical dilatometer instead is able to point can be detected and this can provide information about the surface measure a sinter process completely contact free and guarantees that tension of the liquid.

Heating Microscope 15730 that can be used as well. It defines four characteristic tempera- tures under oxidizing atmosphere. • Observation and analysis of sintering processes • Contact angle determination Functional Principle • Microscopy at high temperatures and under different atmospheres The principle of determination of the ash melting behavior is based on a sample that is melted under defined temperature ramps. The melting temperatures for stone coal are up to 1600°C, for bio mass and wood they are at around 1200°C to 1300°C and for culm containing bio mass they are even lower. The evaluation...
