Measuring method
Even if the kiln drying method is the only measuring
procedure appropriate for verification according to
CEN/TS 14774-1 it is time consuming, in-situ application
can very seldom be carried out; the method also has the
disadvantage that the samples are destroyed. Schaller
GmbH (Ltd.) has developed FS_200-HT Wood chips
moisture meter – a measuring method which provides
exact measuring results within seconds. Yet it is not
possible to develop a measuring device that is ideal
under every single condition; even FS_200-HT has a
certain limited range to provide optimum results. In order
to minimize incorrect applications resulting from that fact
we have provided you
with a list:
IMPORTANT!
Most common reasons for
measuring errors
•
Product temperature NOT b5 and +35 °C
You can not measure wood chips which are
contaminated with ice or snow. Before measuring
you must conditioning the chips at a temp. > +5 °C.
•
Product temperature beyond ambient conditions
The temperature of the measuring device and of the
product should be nearly equal.
•
Wrong switch position
•
Uneven pressing
•
Product pile not thick enough
If the pile of wood chips is to thin (500mm) you get
wrong measuring results.
•
Electrically conductive material
All metallic objects influence the measuring result in
a negative way and must no be positioned within a
range of 500 mm below the sensor area.
