The invention relates to a measuring rod 10 capable of receiving a plurality of instrumentation cables transmitting data to a data processing device, said measuring rod being characterised in that it comprises a section of epicycloidal shape. An outer epicycloidal profile 11 of the shape may be constructed from three isometric arcs A1, A2 and A3 constructed from circles of the same radius. An inner epicycloidal profile 13 of the shape, that delimits an inner space 12 of the measuring rod, may be constructed from three isometric arcs A1, A2 and A3 constructed from circles of the same radius. An instrumentation system for characterising a turbomachine that incorporates the measuring rod is also disclosed. |
