Thermal Diffusivity Thermal Conductivity

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 600 provides a cost effective solution for the temperature of various kinds...

The sample is positioned on a sample robot, located in a furnace. The Accuracy & Repeatability furnace is then held at a predetermined temperature. At this temperature the sample surface is then irradiated with a programmed energy Highest Accuracy (+/-2.2% for thermal diffusivity, +/-4% for specific pulse (laser or xenon flash). This energy pulse results in a homogeneous heat and +/-5% for thermal conductivity) and repeatability (+/-2% for temperature rise at the sample surface. The resulting temperature rise thermal diffusivity, +/-3.5% for specific heat and +/-4% for thermal of the rear surface...

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 Software...

System Design Detector Iris Furnance Sample Carrier Xenon Flash controlled gas control box (2, 3 or 4 gases) can be attached to generate specific atmospheres. The used Nd: YAG Laser has a power output of 10J/pulse. Both the power and the pulse length can be easily adjusted by the Software. The system design includes all safety features to guarantee a secure ope- ration. The LFA/XFA unit can be equipped with 7 different furnaces. All furnaces are easily exchangeable. Xenon Flash Lamp Analyzer The fully motorized sample robot can carry up to 6 samples (10 or 12.7 mm round or 10 mm square) or up...
