Holding Brackets
To mount the 61F-GP-N8 Conductive Level Controller on the
PF083A Track Mounted Socket, use the PFC-N8 Mounting Brackets
attached to the Socket as an accessory.

Application
When using electrodes in sea water or sewage, provide a sufficient
interval (normally 1 m) between the electrodes. If the sufficient inter-
val cannot be provided, employ a low-sensitivity-type Floatless Level
Controller.
When taping one of the electrodes to prevent it from contacting the
other electrodes in water, do not tape the electrode entirely but leave
at least 100 mm of its end uncovered.
When the required length of the electrode is more than 1 m, use a
separator at each joint of two electrodes so as to prevent the elec-
trodes from contacting one another.
Note:
Avoid use of the separators in dust-containing liquids.
Usually, electrodes are used in a set of three: long, medium, and
short. Connect the short electrode to E1, the medium electrode to
E2, and the long electrode to E3. Make E3 at least 50 mm longer
than E2.

Electrodes are in actual contact with the liquid. Standard electrodes
are made of stainless steel and usable in purified water, sea water,
sewage, acid (except acetic acid, sulfuric acid, etc.) and alkaline liq-
uids, although they may corrode depending upon the temperature
and working conditions.
