Abstract

A measuring apparatus for measuring the internal dimensions of a tube such as a pipe in an oil well includes a central body (1) and number of lateral extending measuring arms comprising pivoted links (31, 32). The links are mounted on the body via slider mechanisms (8, 9, 13, 22) so that the displacement of the inner link end provides a measurement of arm extension. The displacement is measured by a variable inductance device (21, 47), the electrical components of which are shielded from external pressure.
