Patent ID: 7178418

Claim:
Segment ( 15 ) of a sensor-supporting element ( 11 ) of a scraper-type device, in which the sensor-supporting element ( 11 ) is assembled from such segments ( 15 ) and forms a hollow body with a cylindrical envelope surface and the scraper-type device can be moved through a pipeline ( 13 ) for the purpose of pipeline testing, whereby the sensor-supporting element ( 11 ) is fitted with sensors ( 21 ) required for the performance of the pipeline testing, characterized in that: the segment ( 15 ) comprises at least a first pair of essentially parallel runners ( 19 a , 19 b ) and a second pair of essentially parallel runners ( 19 c , 19 d ), whereby the at least two pairs of runners are sequentially arranged relative to the direction of motion of the scraper-type device; the first pair of runners ( 19 a , 19 b ) are elastically connected to the second pair of runners ( 19 c , 19 d ) by connecting elements ( 17 ); a sensor plate ( 20 ) for sensors ( 21 ) is arranged between and connected to the first pair of runners ( 19 a , 19 b ); and the segment ( 15 ) is adapted such that it can be connected to additional such segments ( 15 ) by means of a connecting device connecting the segments ( 15 ) so as to form the hollow body with a cylindrical envelope surface.
