FQ90xxx
Heat Flow PLates Type
Technical
Features:
¡Ü For
determining the heat flow density up to max. 150¡ÆC. ¡Ü
Application-oriented designs, consisting of a meander of opposing thermocouples
that are embedded in a substrate. ¡Ü
In case of thick substrates no lateral circulation of the heat flow because
of sufficient meander shell zone. ¡Ü
Software for k value measurement, see page 06.07.
¢Æ 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¢ç connector so that ALMEMO¢ç devices will
immediately indicate the current heat flow density in
W/m2.
