Leakage sensors are connected to level monitors such as the ENW-E12 (item no. 110308xx) and MR-LD6 (item no. 11084413) to detect conductive liquids in the event of a pipe break, for example. If an electrically conductive liquid (e.g. water) gets between the two electrodes, an electrical connection is created that triggers an alarm in the connected ENW-E12 or MR-LD6 level monitor. Color: gray.
