Leakage-monitoring arrangement, in particular at pipe joints

摘要

The invention relates to a leakage-monitoring arrangement, in particular at pipe joints, having a pneumatic sensor and a detector connected to this sensor. The object of the invention is to create an arrangement of this type which has a simple construction of the sensor but nevertheless permits reliable indication for short periods without clogging or obstruction of bores of the sensor influencing the result of the measurement. To this end, provision is made for the sensor (10) to consist of a receptacle (11), open at the top, under the pipeline, in which receptacle (11) a porous layer or diaphragm (15) permeable as a function of moisture is arranged above an air-supply line (20, 35), and for a pressure gauge (23, 38) to be connected in the air-supply line (20, 35). <IMAGE>
