FIELD: investigating or analyzing materials.
SUBSTANCE: device comprises sensors of longitudinal and angular positioning arranged in a cross-section of pipeline parallel one to the other and to the plane of the Roentgen radiation flux. The sensor of longitudinal positioning is mounted a the cross-section in front of the plane of the flux at a distance of 8-10 mm in the direction of movement of the device. The sensor of angular positioning is mounted at a distance of 4-6 mm from the radiation flux, or interposed between the plane of the flux and the plane of the sensor of longitudinal positioning, or from the opposite side of the plane of the radiation flux. The sensor of longitudinal positioning is oriented strictly normal to the inner side of the pipeline, and the sensor of angular positioning strictly points to a point at the inner circumference.
EFFECT: reduced labor consumption and enhanced safety.
