Large-Size Dilatometer | Thermal Expansion Testing System for Large Samples

Large-Size Dilatometer DIL | Thermal Expansion Measurement System for Large Samples

The large-size dilatometer (Macro Dilatometer) is specifically designed for applications where small specimens cannot properly represent material behavior, such as marble, natural stone, and refractory materials. This system accommodates oversized samples and measures their linear thermal expansion under high-temperature conditions, providing highly reliable data for material development, engineering applications, and quality control.

With support for high-temperature testing, multi-sample measurement, and high-resolution displacement sensing, the system is ideally suited for industries requiring strict dimensional stability, including construction materials, refractories, and metals.

Product Overview

The large-size dilatometer enables testing of specimens with large diameters and extended lengths, allowing measurements that more closely reflect real-world material usage. This avoids misinterpretation caused by undersized samples and is particularly valuable for building stones and refractory materials, which often exhibit large dimensions and heterogeneous structures.

Key Features

• Designed for Large Samples: Supports specimens up to 50 mm in diameter and 100 mm in length, ideal for stone and refractory materials.
• High-Temperature Capability: Maximum operating temperature up to 1600 °C, suitable for high-temperature material applications.
• High-Precision Sensing System: Resolution of 0.1 µm ensures accurate thermal expansion curves.
• Multi-Sample Measurement: Allows simultaneous testing of multiple samples to improve throughput and efficiency.

Applications

• Refractory Materials: High-temperature dimensional stability analysis for material selection and process optimization.
• Marble and Natural Stone: Thermal expansion testing for construction materials to prevent thermal stress damage.
• Ceramic Materials: Analysis of sintering behavior and thermal expansion at elevated temperatures.
• Metals and Alloys: Measurement of coefficients of thermal expansion (CTE) for engineering and design purposes.
