TPSYS20 manual v2202 5/75
Introduction
TPSYS20 is an accurate and user friendly system for measuring thermal conductivity. Its main
components are the TP02 thermal needle probe (or its smaller equivalent, model TP08), the
MCU Measurement and Control Unit and software.
This user manual describes the use of the TPSYS20 system in combination with TP02 or TP08.
There are slight differences in requirements for heating time, specimen size and the use of
containers for the specimen. For more details about the TP02 and TP08 thermal needle probes
themselves, please consult the separate TP02 and TP08 user manuals. The general text of the
TPSYS20 user manual covers laboratory experiments. Field measurements are possible as
well, but are less common. These are treated in the appendix.
TP02 and TP08 are designed for measuring thermal conductivities in the range from 0.1 to
6.0
thermal conductivity of a specimen is determined from the step response of the specimen
temperature to heat from a linear heater. The MCU takes care of the measurement and control
process and provides a convenient graphical user interface in the form of a webpage. TPSYS20
is particularly suitable for thermal conductivity measurements in a laboratory environment. If
needed, TPSYS20 can be powered from a 12 V battery, so that it may be used in the field.
TPSYS20 is operated in conjunction with a PC. An intuitive and easy-to-use graphical user
interface allows the user to set measurement parameters, control measurements, view
measurement progress and view and download measurement data.
