ABSTRACT:
A control system for the detection of leaks in insulation-jacketed pipes having measuring probes, each with two electrodes, arranged at sectional intervals and connected to an evaluation circuit. The technical problem resides in the arrangement of the measuring probes on the cold side of the pipes and in the reliable determination of any incidence of leakage, at the exclusion of long-term fluctuations. The heat insulating jacket forms radially open measuring chambers into which measuring probes are removably insertable. Each measuring probe has a plug connector or connection terminals for the evaluation circuit. The electrodes serve as a frequency-determining element of an oscillator.
