Abstract

L'invention se rapporte à un ensemble constitué par un dispositif (2,5) de détection de fissures radiales (6) sur un filtre (1) à particules du type en nid d'abeille, dont la partie filtrante est constituée par un matériau inorganique poreux, ledit filtre à particules comprenant un seul élément monolithique (4) ou étant obtenu par l'association d'une pluralité d'éléments monolithiques, le dispositif étant caractérisé en ce qu' il comprend un matériau conducteur électrique (2) disposé sous la forme d'une bande ou d'un fil sur au moins une partie longitudinale du filtre, solidaire d'un élément monolithique et/ou du ciment de revêtement ou du ciment de joint, et présentant une conductivité électrique supérieure à celle du matériau constitutif de la partie du filtre dont il est solidaire et une résistance à la contrainte inférieure ou égale à celle du matériau constitutif de la partie du filtre dont il est solidaire, ainsi que des moyens de mesure de la conductivité ou de la résistance électrique de la bande ou du fil de matériau conducteur électrique.
