The invention concerns a module comprising an air pressure sensor (3) with an air intake (4), a printed circuit card (5) support, whereon the sensor (3) is mounted, and an anti-pollution filter (6) protecting the air intake (4). The filter (6) extends through said card (5) and is in contact with the sensor (3) through a contact surface (14, 15) forming a single sealing joint surface providing tightness to the air intake (4). The invention is particularly applicable to modules for measuring a motor vehicle tyre pressure.
Le module comprend un capteur de pression d'air (3) avec une entrée d'air (4), une carte (5) support de circuit imprimé, sur laquelle est monté le capteur (3), et un filtre anti-pollution (6) de protection de l'entrée d'air (4). Le filtre (6) s'étend à travers ladite carte (5) et est en contact avec le capteur (3) par une surface de contact (14, 15) constituant une unique surface de joint d'étanchéité contribuant à l'étanchéité de l'entrée d'air (4). L'invention s'applique bien aux modules de mesure de pression de pneumatique pour véhicule automobile.
