Description

Level relay for level monitoring, using 2 or 3 electrodes 1 SPDT Standard relay for level monitoring with 1 and 2 threshold values, infinitely variable limit values, 1 SPDT and isolating transformer according to VDE 0550. Function: The electrodes are connected to the relay. Should the tank be made of a conductive material, it can be used as a third electrode (For connection see wiring diagram). AC current is used in order to avoid polarisation, electrolysis and undesired oxidation of the electrodes. To minimize false relay switching (e.g. pollution of the probes, humidity ….), the switching sensitivity can be adjusted to the conductibility of the respective media.
