Control of conductive liquids (tap water, sea water, sewage,
chemical solutions, coffee, ice cream, etc.)
The relay is energized when the level falls below the low level
probe. It de-energizes when the high level probe is reached.
The NRU will also control a single level. In this case, a single
probe is used and the relay operates when the probe is not
immersed. The Max terminal is connected to common with a
jumper.
In either case, a common electrode is needed if the container
t
is non-conductive.
