Sensor cable for detection of leaks in pipeline

摘要

The sensor cable contains two sensor conductors (2,3) forming a moisture detector which extends along the pipeline. The sensor conductors are mounted at different points on the surface of a central cylindrical core (1).The conductors can be mounted diametrically opposite each other on the core. Cylindrical distance pieces (4) arranged between the sensor conductors and in the peripheral direction around the core are of larger dia. than the sensor conductors. The distance pieces can be insulated electrical conductors.
