LEAKAGE MONITORING SYSTEM FOR SPACE-ENCLOSING OBJECTS AND COUPLING REGIONS LOCATED THERE BETWEEN

摘要

A leakage monitoring system is provided for space-enclosing objects, such as pipes, hoses or containers having an exterior wall. The leakage monitoring system includes at least one electrically conductive element that acts as a leakage sensor and is mounted on the exterior wall or integrated therein. In order to make simple and reliable monitoring of imminent or already occurring leakages possible, even for extensive wall regions, and specifically in as universal a manner as possible for different types of media, the electrically conductive element is a component of a measuring bridge which contains a device for evaluating the bridge voltage and which is powered by a voltage source has an operating voltage containing both AC voltage components and DC voltage components.
