Bestimmung des Wärmestroms
Der Wärmestrom, der die Probe durchdringt, lässt sich durch Messung der elektrischen Leistung der mittleren Heizplatte sehr genau bestimmen. Des Weiteren wurde eine Änderung an der messtechnischen Erfassung der Leistung der mittleren Heizplatte vorgenommen. Ursprünglich war die Messung von Stromstärke (0 bis 20 A) und Spannung (0 bis 32 V) unter Verwendung der Monitorausgänge des Netzteils der Gleichstromversorgung vorgesehen. Um die Messgenauigkeit zu erhöhen, wurden zwei Eingangsmodule direkt an den Heizleiter der mittleren Heizplatte angeschlossen. Die Spannungsmessung wurde nach Testversuchen und Vergleichsmessungen auf einen Bereich von 0 bis 10 V, die Stromstärkenmessung auf 0 bis 5 A skaliert. Durch die galvanische Trennung der Spannungs- und Stromstärkemessung können Störeinflüsse eliminiert werden.

Determination of the heat fluxThe heat flux penetrating the sample can be determined very precisely by measuring the electrical output of the Middle plate. In addition, a change to the metrological acquisition of performance of the Middle plate was made. The measurement of current (0 to 20 A) and voltage (0 to 32 V) was originally intended by using the monitor outputs of the power supply of the power supply. To increase accuracy, two input modules were directly connected to the heating cable of the Middle plate. The voltage measurement was after test trials and comparative measurements on a range from 0 to 10 V, which scale to 0 to 5 A current measurement. The galvanic separation of the voltage and current measurement, interference can be eliminated.

Determination of the heat flow
, the heat flow which passes through the sample, can be determined very accurately by measuring the electric power of the central heating plate. Furthermore, a change was made ​​to the metrological detection of the power of the central heating plate. Originally, the measurement of current was (0 to 32 V) is provided (from 0 to 20 A) and voltage using the monitor outputs of the power supply of the DC power supply. To increase the measurement accuracy, two input modules are connected directly to the grid lines of the central heating plate. The voltage measurement is scaled according to Test experiments and comparative measurements to a range of 0 to 10 V, the current measurement to 0 to 5 Å. The galvanic isolation of the voltage and current measurements Interference can be eliminated.
