Installation
The isolation of the electrode rod may not be damaged resp. removed excepted at the electrode tip.
The electrode rods can be cut arbitrarily by a tong or a saw. After cutting the electrode rod, remove 10 mm of
the isolation. The electrode may not be mechanically forced at the cutting, to avoid damaging the isolation.
Installation notes
Drive the system pressure free prior installation resp. deinstallation of the device and avoid high temperatures
to avoid injuries.
Consider enough installation space outside the container, to insert the electrode probe into the plant without the
use of force.
Install the device if necessary into a bypass if dense heavy foam, wild turbulences or foamed liquids can occur.
Install the electrode probe in such a position in the container, where no strong forces to the side, like e.g. by
mixer or near fill-in openings, can have an effect to the electrode rods.
This is especially important for especially long electrode rods.
The non-isolated electrode tips, when mounted, may not make a contact to the wall of the container, if this is
made of metal or electrically conductive plastic.
Electrode rods longer than 0,5 m must be stabilized among each other or against the wall of the container,
especially if the filling material is strongly fluctuating.
Use for the stabilization suitable isolating spacers.
The distance between the spaces should be not more than 0,5 m.
At horizontal side mounting into a container or also into a pipe for stability reasons the length
of the electrode rods should be not more than 200 mm.
At wider electrode rods (8 mm) the length can be longer.
At a horizontal mounting the electrode rods should be installed at an angel with the
electrode rod tip below (approx. 20°), to allow an easier flow-off of filling material
residues and by this to avoid the coat-forming.
At horizontal pipelines the length of the electrodes is limited by that way, that in a empty
pipe, also in the case of liquid residues, the electrically conductive liquid connection
between the two electrode rods can disconnect.
Otherwise and empty pipe can be detected as filled.
The tightening of the process connection may only be done at the hexagon by a suitable spanner. The
maximum permitted torque strength is 100 Nm.
The screw in of the process connection by using the connection housing is not permitted.
Maintenance
The device is free of maintenance.
The isolation of the electrodes should be checked regularly and also a possible coating at the electrode tips
should be removed.
A non-conductive coating at the metallic electrode tip can effect error behaviour because no current can flow
although the electrically conductive filling material makes a connection.
