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
