Abstract
1414884 Electro-physical measurements COMMISSARIAT A L’ENERGIE ATOMIQUE 19 Sept 1973 [6 Oct 1972] 43932/73 Heading GIN In the detection of the variations in the crosssection of a tube by means of a cylindrical probe carrying capacitive transducers inserted within the tube, the probe is pneumatically supported so that its axis coincides with that of the tube and a torque is applied to the probe about its axis to align the probe with the major and minor axes of the tube. Probe 1 comprising a casing 4 having an extension 5 which is rotatably mounted in collet 6 of a casing holder carries four capacitive transducers 13 arranged in pairs at opposite ends of two perpendicular diameters respectively, each transducer comprising a central electrode surrounded by a circular guard ring electrode, Fig.2 (not shown) and being connected via leads 19 to a bridge circuit. Duct 10 allows compressed air to be passed to cavity 11, acting as a manifold, and thence via radial ducts 12 to the spacing between casing 4 and tube 2 being tested to form an air cushion whereby the casing 4 floats freely within tube 2 so that the longitudinal axes of the tube and casing coincide. The front end of casing 4 is provided with two recesses 21, 22 connected by lateral duct 23 which co-operate with end cap 24 to form two chambers. End cap 24 is formed with four slots 27, 28, 29 and 30 so that some of the compressed air passing through manifold 11 can escape radially from the recesses 21, 22 and act directly on the walls 3 of tube 2 to generate two opposing torques on the casing 4. In this way the casing 4 is rotated by the torques until the reference plane X, X
