Kind Code:
A
Abstract:
To provide a fixing jig capable of accurately positioning a measurement unit to a metallic columnar object.SOLUTION: A fixing jig 1 fixes a non-contact type measurement unit 2 for measuring a crack or a board thickness to a metallic column 1000. The fixing jib includes an attachment part 11 and a sensor arrangement part 12. The attachment part 11 has a linear attachment part 11b which is oppositely arranged along an intersection line 1000b where a plane S1 including a central axis A of the metallic column 1000 intersects with a side surface 1000a. The attachment part 11b can be attached to the metallic column 1000 in a state of arrangement opposed to the intersection line 1000b. The sensor arrangement part 12 is formed by projection from the attachment part 11 in a direction parallel to the attachment part 11b, and has an arrangement part 12ap. In the arrangement part 12ap, the measurement unit 2 having a plurality of magnetic sensors 31 aligned along an axis B can be arranged so as to allow the axis B to be on the same plane S3 as the attachment part 11b and also to be in parallel with the attachment part.SELECTED DRAWING: Figure 4
