High-precision Thermal Expansion Measurement for Ceramics & Solids AZA1269

Description

Purpose of Linear Thermal Expansion Testing

Thermal expansion analysis is essential for evaluating how materials behave when exposed to elevated temperatures. Improper expansion characteristics can lead to cracking, warping, loss of mechanical integrity, or system failure in real-world applications.

The AZA1269 enables accurate determination of:

• Linear thermal expansion coefficient

• Expansion and contraction behavior over temperature

• Phase transitions and structural changes

• Material suitability for high-temperature applications

High-Temperature Furnace System

At the core of the AZA1269 is a robust silicon carbide heating furnace (I Squared R, USA), capable of continuous operation at 1400 °C. The furnace is mounted on a guided rail movement system, allowing smooth, controlled travel for easy specimen loading and unloading while maintaining precise alignment during measurement.

Furnace Design Highlights

• Silicon carbide heating elements for uniform heat distribution

• Continuous operation at maximum temperature

• Guided rail mechanism for smooth and safe furnace travel

• High thermal stability for repeatable test cycles

High-Precision Expansion Measurement

Linear displacement is measured using a high-sensitivity LVDT system (German make – MASSETRON), providing 1 micron resolution. This enables sub-micron detection of dimensional changes, even in materials with very low expansion coefficients.

Measurement System Features

• LVDT-based displacement measurement

• Measuring range: 0 to 2000 microns

• High signal stability at elevated temperatures

• Recrystallized alumina probe and tube for thermal compatibility

Advanced Control & Software Integration

The AZA1269 is supplied with LabVIEW-based custom software, offering full digital control, automation, and data logging. The intuitive interface allows users to define heating profiles, monitor expansion curves in real time, and export data for analysis and reporting.

Control & Software Capabilities

• Closed-loop PID temperature control

• Real-time expansion vs temperature graphing

• Automated test sequencing

• Digital data storage and export

• USB PC interface

A dedicated PC with inkjet printer is included for complete standalone operation and report generation.

Industrial-Grade Safety & Temperature Regulation

Safety and reliability are integral to the AZA1269 design. The system incorporates industrial-grade electrical and thermal protection components to ensure safe long-term operation at high temperatures.
