Hot Disk method for measuring thermophysical properties is subject of a workshop to be held at the Express/Holiday Inn, Milton Keynes on Tuesday 10 May 2005
Heath Scientific announces its first workshop on the Transient Plane Source method (hot disk) for measuring thermophysical properties, to be held at the Express/Holiday Inn, Milton Keynes on Tuesday 10 May 2005.
Registration can also be made online.
Please note the deadline for registration is 30 April 2005.
The Hot Disk method is used for determining thermal transport properties of materials such as metals, alloys, ceramics, composites, minerals, plastics, paper, fabrics, powders, high viscosity fluids, building materials, biomaterials and multi-layered materials.
Features of Hot Disk include:.
Measure thermal conductivity, thermal diffusivity and heat capacity.
Study materials with thermal conductivities from 0.005 to 500W/mK.
Covers a temperature range of 30 to 1000K.
Based on a patented transient plan source (TPS) technique.
Advantages of Hot Disk include:.
Fast - direct measurement of heat propagation generated by sensor into material.
No need to wait for a temperature gradient to form across the sample.
Minimal sample preparation.
Only requirement is two fairly flat surfaces facing the sensor.
Only data stemming from heat propagation in the sample material are used for calculation - removes errors associated with sensor cladding or small air pockets between sensor and sample.
Not affected by contact resistance - in static methods, resistance builds up between the thermocouple and sample surface
