Principles
Operating principle
Control of maximum and/or minimum levels of conductive liquids (tap water, sea water, waste water, chemical solutions, coffee etc).
The principle is based on measurement of the apparent resistance of the liquid between two submerged probes. When this value is lower than the preset threshold on the unit front face, the output
relay changes state. To avoid electrolytic phenomena, an AC current funs across the probes. Applications found in environmental, chemical industries and food technology etc.
Regulation of two levels : Minimum / Maximum
The output relay changes state when the level of liquid reaches the maximum electrode, with the minimum electrode submerged. It returns to its initial state when the minimum probe is no longer in
contact with the liquid.
Note
The probe wire (max length 100 metres) does not have to be screened, but avoid mounting it in parallel with the power supply wires. A screened wire can be used, with the screening connected
to the common.
