Abstract

A method and a device for detecting leaks in components conducting liquids by a sensor reacting to leaks. The component to be monitored is inserted into a closable envelope containing the leaked liquid. Electrodes are embedded into the envelope. The resistance and/or the capacitance between the electrodes is changed if leaking liquid enters the closed envelope. With a sensor connected to the electrodes, which reacts to the resistance and/or capacitance changes, a display and/or alarm signal is triggered. It is possible to monitor the entire component for leaks.
