INSPIRION DL Series

Method Overview

The dimensional stability of materials under thermal stress is a fundamental property that directly impacts the performance, reliability, and safety of finished products. Dilatometry is the precise measurement of dimensional changes in solids, liquids, and powders as a function of temperature.

This technique is indispensable for determining key parameters such as the Coefficient of Linear Thermal Expansion (CLTE), glass transition temperatures ( $T_{g}$ ), sintering behavior, and phase transformation points. From ensuring the structural integrity of aerospace alloys and high-temperature ceramics to characterizing the processing behavior of polymers and composites, dilatometry provides critical data for materials research, quality control, and process optimization..

INSPIRION DL Series Dilatometers

The INSPIRION DL series offers high-precision solutions for measuring thermal expansion and contraction across a wide temperature spectrum. The series features two specialized models designed for specific application ranges: the high-temperature INSPIRION DLH and the low-temperature INSPIRION DLV.

Model Overview & Applications

1. INSPIRION DLH (High-Temperature Dilatometer)
A benchtop system engineered for analyzing materials under extreme heat.

Primary Applications: Metals, alloys, ceramics, graphite, high-temperature composites, and certain plastics.
Ideal For: Research on sintering kinetics, refractory behavior, phase transformations in metals, and high-temperature stability of advanced materials.

2. INSPIRION DLV (Low-Temperature Dilatometer)
A floor-standing system designed for precise analysis at sub-ambient and low-to-moderate temperatures.

Primary Applications: Polymers, elastomers (rubbers), light alloys, composites, and any material where low-temperature behavior is critical.
Ideal For: Determining glass transition temperatures ( $T_{g}$ ), studying contraction and expansion in plastics, and characterizing materials used in cryogenic or variable climate conditions.
