Miniature heat flux sensor FQAx

high-temperaturelow thicknessmonitoring

Heat Flow Plates • For determining the heat flow density up to max. 150 °C. • Application-oriented designs, consisting of a meander of opposing thermocouples that are embedded in a substrate. • In case of thick substrates no lateral circulation of the heat flow because of sufficient meander shell zone. • Each heat flow plate has been assigned a calibration value, which corresponds to the heat flow density in W/m² when the plate provides an output of 1mV. The calibration value will be stored as factory-setting in the ALMEMO® connector so that ALMEMO® devices will immediately indicate the current heat flow density in W/m². Digital heat flow plate •This automatically corrects the heat flow plate’s temperature coefficient using a miniature NTC sensor integrated in the heat flow plate for the purpose of measuring the plate’s mean temperature. •It measures heat flows and temperatures using a A/D converter incorporated in the ALMEMO® D6 plug. •Two measuring channels are programmed (at our factory). •Plate’s mean temperature (°C, t) Heat flow, temperature-compensated (W/m², fq).
