FIELD: transportation; control devices.
SUBSTANCE: invention relates to the field of pipelines monitoring, in particular, to protection of an in-tube device and a pipeline against a possible explosion during diagnostic transmission of an in-pipe device in a pipeline. Invention includes at least one section, which contains explosion-proof tight shell including housing, cover front, sealing rings ensuring tightness of explosion-proof sealed shell, battery cassette and electronics unit. Unit comprises measurement equipment and hardware for recording diagnostic information, wherein it is configured to control the battery cassette, in which independent power sources are installed. Electronics unit also includes an intrinsically safe unit which includes three diodes connected in series to electric circuits of the explosion-proof in-pipe device and having an outlet for external electric connectors of the flameproof tight shell.
EFFECT: improving explosion safety during operation of in-pipe device in pipelines.
