Abstract

Dispositivo para medir el juego (J) existente entre las puntas (3) de los álabes móviles (2) de una corona de álabes y la pared interior (4) del cárter (5) que rodea a la citada corona de álabes en una turbomáquina, caracterizado por el hecho que comprende una sonda (7) susceptible de ser montada radialmente sobre el cárter (5) y de la que una extremidad, al menos, está realizada en un material susceptible de ser desgastado por abrasión por las puntas (3) de los álabes (2) en rotación, un circuito impreso (12) dispuesto en el plano medio de la susodicha sonda (7) que contiene el eje de rotación (X) de la citada corona de álabes, comprendiendo este circuito impreso (12) una pluralidad de circuitos eléctricos (20a a 20e) adyacentes en U cuyas bases (22a a 22e) están dispuestas en una extremidad de sonda susceptible de ser desgastada por abrasión por las puntas (3) de los álabes y están situadas a profundidades distintas (za a ze) con respecto a un nivel de referencia (24) que define la pared(4) interior del cárter (5), y medios (9) para reconocer los circuitos eléc-tricos en U cortados por abrasión y los circuitos eléctricos intactos.
