Device for measuring an internal or external profile of a tubular component

A device for measuring an external or internal profile of an end portion of a tubular component, comprising:

• a first sensor for making a radial measurement of the tubular component with respect to a pre-defined reference;
• a support which can drive the first sensor in a circular trajectory in a predefined plane orthogonal to the principal axis of the component, wherein the support comprises a principal body that can be attached to the component via a releasable attachment means and a shaft which is movable in rotation with respect to the body on which an arm carrying the first sensor is attached to allow displacement of the first sensor in a circular trajectory inside or about the tubular component;
• and
• a second sensor for measuring an angular position of the first sensor for each radial measurement of the first sensor, the radial and angular measurements of the first and second sensors allowing the profile of the component in the pre-defined plane to be determined.
