FP2C CONDUCTIVITY METER HOT WIRE

EFFUSIVITY METER HOT SURFACE

DIFFUSIVITY METER HOT RING

NeoTIM commercialize a device for characterizing the thermal conductivity, diffusivity and thermal effusivity of insulating materials called FP2C.
This device relies on :
• the hot wire method for measuring thermal conductivity
• the hot ring method for measuring thermal diffusivity
• the hot plane method for measuring thermal effusivity

OPTIONS

Hot Wire probe

Conductivity from 0,02 to 5 W.m-1.K-1
Measuring temperature from –60 to 100 ° C and 100 to 250 ° C with a specific optional probe
Samples: at least 60x40 mm, from several millimeters thick for the insulators to a few centimeters for the more conductive

This principle of probe and device was initially developed by the CSTB (Centre Scientifique et Technique du Bâtiment). It is also derived from ASTM D5930-97 (Standard Test Method for the Thermal Conducitivity of Plastics by Means of a Transient Line Source Technique) and RILEM AAC 11-3.

Hot Surface probe

Thermal effusivity: from 20 to 10,000 J.m-2.K-1.s-1/2
Measurement temperature: -60 to 100 ° C
Minimum sample size: 50 x 50 mm, from a few millimeters thick for an insulator to a few centimeters for a conductor

Hot Ring probe

Diffusivity from 0.1 to 4mm².s-1
Measuring temperature from –60 to 100 ° C
Samples: at least 25 x 25 mm, from a few millimeters thick for an insulator to a few centimeters for a conductor.

Needle probe

Conductivity from 0,02 to 5 W.m-1.K-1
Measuring temperature from -20 to 100 ° C
Samples: at least covering the metal part of the probe, from a few millimeters thick for an insulator to a few centimeters for a conductor.

The principle of this shock probe is to produce locally a low heating of the material (a few degrees above the sample) and to measure this temperature rise over time (duration of a few minutes). By mathematical processing of this signal integrated in the supplied software, the identification of the thermal conductivity is achieved.
