Usage and Intent

The method involves uniform irradiation of a small, disc-shaped specimen over its front face with a very short pulse of energy. The time-temperature history of the rear face is recorded through high-speed data acquisition from a solid-state optical sensor with very fast thermal response. Thermal diffusivity is determined from the time dependant thermogram of the rear face. Thermal conductivity can be computed from measured values of thermal diffusivity and specific heat capacity, with the additional knowledge of density. Thus, a system can automatically determine thermal conductivity using the measured (or separately entered) heat capacity and thermal diffusivity, with separately entered density data. A unique feature of the system is the full-time pulse mapping and recording capability that allows precise pulse shape and pulse width correction calculations.

Environment can be air, or inert gas. The furnace assembly is completely gas tight.

Simple to operate and safe to use

The system is suitable for research and development programs, as well as quality control. It is easy to maintain and very economical to operate in terms of consumables. The pulse module is integral, forming a compact bench top unit. The output of the HSXD is channeled through a proprietary patented wave guide to any of the specimens. Pulse delivery through the wave guide produces outstanding flux uniformity that greatly improves the data.

Modular architecture

The Flashline perhaps the most flexible system of its kind. It allows the addition of other furnaces at a later date to grow with changing needs. Including the multiple sample testing option pioneered by Anter. This feature not only produces a several times increase in productivity, but also makes the optional specific heat capacity measurement more reliable. A variety of specimen sizes and shapes can be accommodated. Testing time is only minutes at thermal equilibrium. Automatic sequencing of multiple tests ensures high statistical reliability for data obtained.
