Nowadays, development of new materials requires precise
and fast measurements of physical properties.
Sometimes, it's difficult to find correct valors in
documents. |

The TPS Technology, or Transient Plane Source, was
developed
in order to measure thermal conductivity and thermal diffusivity
on various materials, with a great precision.
Created at the beginning of 90's by Dr Silas Gustavsson, this
innovative technology has revolutionized measurements of
thermal properties linked to warmth transfer, in global
laboratories and other research institutes. |

Indeed, thanks to special TPS sensors,
we can realize thermal conductivity, thermal diffusivity and specific
heat
capacity measurements with an increased sensibility and precision.
They can be made in varying environments and a
wide range of temperature. The TPS Technology provides your
necessary valors, without the influence of thermal resistance,
without samples preparation and in very short time. |

To realize measurement, place the Hot Disk sensor between
two pieces of the sample in question, with parallel faces. The
sensor is a warmth
transmitter and a temperature
sensor.
It's also possible to realize measurements in an
asymmetrical system (only 1 sample to characterize). The sensor
is put between a single sample piece and another piece of material,
typically Polystyrene, with known thermal transport properties. This option is appropriated to measurements of quality
controls . |

The principle doesn't change for measurements on liquids, powders, or pastes.
The sensor is simply inserted into the material, or pasted on both sides of the probe. |

When the set-up of samples is made, entry your parameters
in the Hot Disk Analysis software.
With only one manipulation, you obtain the exact
measurements of thermal conductivity, thermal diffusivity and
specific heat capacity

Several Industrial
Groups, Research Laboratories and prestigious Universities
have chosen the TPS technology. |
