Leakage monitoring system for space surrounding the objects and, on the coupling areas located between them, and associated method

摘要

A leakage monitoring system (2) for space surrounding the other objects, such as, for example, tubes (4), hoses or container with a surrounding wall (6) has at least one, which is effective as a leakage sensor (8), on the surrounding wall (6) mounted or in this integrated electrically conductive element. In order to also in the case of large-area wall regions of a simple and reliable monitoring for imminent or to make it possible to already leakages, which takes place, and this as universally as possible for the various kinds of media, according to the invention, the electrically conductive element is an integral element of a measuring bridge (12), the an evaluation device (20) for the bridge voltage (v_Measuring) , and the by means of a voltage source (18) with an operating voltage (u_G) is supplied, which contains both filter alternating current components as well as dc voltage components.
