APPARATUS FOR PIPELINE INSPECTION

摘要

A sensor assembly for pipeline inspection is provided. The sensor assembly comprises a sensor arm configured to mount the sensor assembly to a pipeline inspection tool and a sensor carrier configured to support a magnetic flux leakage sensor, the sensor carrier being pivotably coupled to the sensor arm by a pivot pin, wherein the sensor arm comprises a first end configured to connect the sensor assembly to a pipeline inspection tool, a distal end adjacent to which the sensor carrier is secured, and multiple elongate sections which cooperate with one another to capture the pivot pin at the distal end of the sensor arm and thereby secure the sensor carrier for movement with the sensor arm.
