Description
The level electrodes NRG 21-11, NRG 21-51 are level
sensors for giving a continuous measurement of electrically
conductive and non-conductive liquids in vessels.
The level electrode can be used in combination with the
following level switches/controllers: NRS 2-50, NRS 2-51,
NRR 2-50, NRR 2-51, NRR 2-52 and NRR 2-53.
Function
The level electrode and the electronic module NRV 2-29
work according to the capacitance measurement principle
and translate the level changes into a level-dependent cur?
rent signal, with the length of the electrode rod determining
the measuring range.
The level electrode is installed inside the vessel or in an
external level pot. If the equipment is installed inside the
boiler or vessel, a protection tube provided on side ensures
correct functioning.
The level electrode can be used in electrically conductive and
non-conductive fluids
