<p>The inventive sensor carrier for an in-tube inspection device is embodied in many variants and provided with mounting seats for monitor sensors sensible to any diagnostic parameters of a pipeline. Said invention is characterised in that the carrier comprises a large number of sensor holders which are cinematically connected to each other and are capable of withstanding an elastic compression in a radial direction away from the axis of said carrier. The holders are embodied in the form of elastic annular elements or in the form of ranges of elements which are connected to each other and pressed against the wall of the pipe line, or fixed to elastic elements in the form of collar seals or sectors of seal, and / or connected to a flexible body. Elastic spacer gaskets are arranged on the holders between sensors and the inner surface of the pipeline. The inventive carrier makes it possible to improve the inspection effectiveness of pipelines with geometrical defects in the cross section thereof by means of a large number of elements (holders) provided with the mounting seats for sensors, by separating the functions between the pressure of the sensors against the inner surface of the pipeline and the bending around the geometrical defects in the cross-section thereof, by reducing the space variations between the wall of the pipeline and the sensors and the fraction thereof in said space since the orientation of the sensors with respect to the inner space of the pipeline can be altered when the carrier passes by the geometrical defect in the cross-section of the pipeline.</p> |
