FIELD: signalling.
SUBSTANCE: invention relates to the field of alerting of the appearance of a conductive liquid. The technical result of the claimed technical solution is achieved by the claimed solution providing a sensor cable consisting of two insulated and two non-insulated conductors, and a measuring unit containing a microcontroller, keys controlled by signals from the microcontroller, current-to-voltage converters, an analogue-to-digital converter, a graphic display apparatus, a type 485 interface generator, a radio communication module, a relay for signalling about the presence of a conductive liquid, a relay for signalling about a fault in the sensor cable; wherein all four conductors are structurally combined into a single long-length element of the sensor cable connected with the measuring unit.
EFFECT: increase in the reliability of determining the presence of a conductive liquid in places critical to the presence thereof.
