Abstract

L’invention concerne un procédé de test de l’entrefer (E) entre un capteur (1) de rotation d’un arbre tournant (30) d’une turbomachine et une roue phonique (2) montée sur ledit arbre (30), le capteur de rotation étant à reluctance variable et comprenant une première voie (A) de mesure d’une première tension VA et une deuxième voie (B) de mesure d’une deuxième tension VB, le procédé étant mis en œuvre au moyen d’une unité de commande (3) connectée au capteur (1) de rotation, l’arbre tournant (30) ayant un balourd résiduel nominal (bn) et étant mis en rotation à une fréquence de rotation (fN1), le procédé comprenant les étapes suivantes : - mesures simultanées de la première tension VA et de la deuxième tension VB ; - comparaison des première et deuxième tension à une tension nominale (Unominale) de manière à évaluer comment l’entrefer (E) est réglé afin d’évaluer s’il peut tolérer un balourd de l’arbre tournant supérieur au balourd résiduel nominal.
