DIL L76
Robust Economy Horizontal Dilatometer
Description
On point
The LINSEIS DIL L76 Dilatometer series serves as a primary instrument for measuring the Coefficient of Thermal Expansion (CTE) in various materials, including ceramics, bricks, tiles, porcelain, and building materials. It is also extensively utilized for quality control applications in both the ceramics and metal industries.
One notable application is in the sintering process, especially in the pre-firing stage of porcelain cups. The dilatometer’s data curve is instrumental in determining the optimal temperatures for specific sintering stages.
What sets this instrument apart is its long history, having been developed and manufactured by LINSEIS since 1955, making it a highly reliable choice. It covers an expansive temperature range, spanning from room temperature (RT) to 1000°C, 1400°C, and 1600°C, with user-exchangeable furnaces. The measurement systems are constructed from materials such as quartz glass (up to 1100°C) and Al2O3 (up to 1600°C).
The sensor employed is a high-precision LVDT (linear variable differential transformer) with infinite resolution. Combined with the 32-bit LINSEIS WIN-TA / WIN-DIL software package, the Dilatometer offers an exceptional solution for standard quality control CTE measurements.
This versatile instrument enables the measurement of various physical properties, including:
- CTE (Coefficient of Thermal Expansion)
- Linear Thermal Expansion
- Alpha Physical (thermal expansion coefficient)
- Sintering Temperature
- Phase Transformations
- Softening Points
- Decomposition Temperatures
- Glass Transition Temperatures
The LINSEIS DIL L76 Dilatometer series stands as a reliable and precise tool, serving a wide range of industries and applications by offering insights into material behavior under varying temperature conditions.

Applications
Applications example: Glass sample, softening point
The glass sample underwent a measurement using the softening-detection feature. In this scenario, the heating ramp concludes when either the predefined target temperature is achieved or when the sample’s shrinkage reaches a specific threshold. In this particular run, the threshold was set at -100µm, meaning that when the measured change in length falls 100µm below the maximum value of the ongoing heating segment, the heating process halts, and the subsequent cooling segment is initiated. This method provides a straightforward and secure means of detecting the softening point.
