Thermal Diffusivity, Thermal Conductivity Information of the thermo physical properties of materials and heat advantages of this non-contact and non-destructive measurement transfer optimization of final products is becoming more and more vital for industrial applications. Over the past few decades, the flash method has developed into the most commonly used technique for LINSEIS offers a variety of instruments to measure the Thermal Diffusi- the measurement of the thermal diffusivity and thermal conductivity vity. The XFA 300 provides a cost effective solution for the temperature of various...

The sample is positioned on a sample robot, located in a furnace. The Absolute technique furnace is then held at a predetermined temperature. At this temperature the sample surface is irradiated with a programmed energy pulse The method used is an absolute measurement technique (for thermal (laser or xenon flash). This energy pulse results in a homogeneous tem- diffusivity) hence there is no need to calibrate the system. perature rise at the sample surface. The resulting temperature rise of the rear surface of the sample is measured by a very sensitive high speed IR detector and thermal...

All thermo analytical devices of LINSEIS are PC controlled, the individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The LINSEIS 32 - bit soft- ware encounters all essential features for measurement preparation, execution and evaluation, just like with other thermo analytical experi- ments. Due to our specialists and application experts LINSEIS was able to develop this easy understandable and highly practical software. General Software Evaluation...
