3UG3207-3A three-pole wire electrode
The 3UG3207-3A three-pole wire electrode can be used for two-point filling level controls in
an insulating tank. In addition to the common reference electrode there is one electrode for
the min. value and one for the max. value. The three-pole wire electrode has a length of 500
mm.

Note
The wire electrode can be cut to the required length or bent before or after installation. The
Teflon insulation must be stripped back about 5 mm.
3UG3207-2A two-pole wire electrode
The 3UG3207-2A two-pole wire electrode can be used for two-point filling level control in a
tank if the conductive tank is used as a reference electrode. The probe can also be used for
alarm messages on overflow or undershoots. The two-pole wire electrode has a length of
500 mm.
