Abstract
Dispositif fiable et entièrement textable de contrôle du déplacement axial d'un rotor de turbine. Il comprend deux buses 19 et 21 qui dirigent des jets d'air sur les faces opposées d'une bague 18 solidaire d'un arbre de turbine 13 dont on désire contrôler le déplacement axial, ce déplacement modifiant la contre-pression qui apparaît dans les buses, et un circuit pneumatique qui traite cette information de façon à indiquer le déplacement axial de l'arbre. Application aux turbines à vapeur de centrale thermique.
