Fig. 6: POINTRAC 31 as level detection (top view)
POINTRAC 31 lends itself well for level detection of bulk solids with
low density. Mount the instrument horizontally at the height of the
requested switching point.
Mount the source container VEGASOURCE displaced by 90° in order
to get the widest possible radiation angle.
When the sensor is covered by the medium, the radiation damping
is considerably stronger - hence, the switching point is all the more
reliable.
If the max. ambient temperature is exceeded, you must take suitable
measures to protect the instrument against overheating.
You can protect the instrument by providing a suitable insulation
against the heat or mounting the instrument further away from the
heat source.
Make sure these measures are taken into account already in the plan-
ning stage. If you want to carry out such measures later on, contact
our specialists to ensure that the accuracy of the application is not
impaired.
If these measures are not sufficient to maintain the max. ambient
temperature, you could consider using the water cooling system we
offer for POINTRAC 31.
The water cooling must also be included in the calculations for the
measuring point. Contact our specialists regarding the dimensioning
of the water cooling.
