Cable electrode in solids
Dependent on the kind of solid and position or
the kind of filling the cable electrode can "float“
despite of the gravity weight. The electrode
(cable) is pushed by the solid to the vessel wall
or to the top and wrong measured values are
caused. This should be avoided with
continuous measurement.
In this case use a fixing weight to fasten the
cable electrode.
When fastening the cable electrode avoid high
tensile strengths. Appropriate fixing spring
avoiding overloading of the cable is listed in
our pricelist as accessory.
Continuous electrodes
With electrodes, delivering continuous
measured values, the electrode must only be
installed vertically. Should the installation from
top not be possible, the electrodes can also be
mounted laterally.
When in the installation place of the electrode
there are struts or a roof, you should check if a
rod electrode with the required length can be
mounted. If mounting of a rod electrode is not
possible, use a cable electrode.
Under the accessory in our pricelist you find a
screening tube and a closing cone or a bent
rod electrode by which the electrode can be
also mounted laterally. Choose the length (L) of
the screening tube such that no product
bridges can be built between cable and vessel
wall and that the electrode cable cannot touch
the vessel wall due to product movements. Use
a fixing weight.
