Abstract
A coaxial cable and a bare wire are aligned in parallel relationship and affixed within insulation covers which have openings therein so as to partly expose both the bare wire and the outer conductor of the coaxial cable at the atmosphere, forming a leak detecting sensor. By the use of resistance meters, the core wire of the coaxial cable is utilized to detect both the presence and the location of a leak.
