Abstract

L'invention concerne des manomètres à ressort tubulaire pour différents paliers de pression, avec ou sans remplissage de liquide et pour raccordement arrière ou radial à un point de mesure, constitués d'un boîtier, d'un connecteur métallique destiné à relier le manomètre à ressort tubulaire à un point de mesure ainsi que d'un système de mesure relié de façon mécanique et conducteur de pression au connecteur, doté d'un ressort tubulaire et d'un système indicateur. L'invention a pour but de fournir un système d'adaptation avec lequel la multitude de variantes de manomètre dans une gamme de manomètres peut être conçue avec une structure modulaire à partir des variantes de base des différents composants de manomètre. Le but est atteint du fait qu'une plaque d'adaptation centrale (7) existante à l'intérieur du boîtier (2) possède un point de raccordement (8) détachable ou non détachable pour le connecteur (3) et un point de raccordement de ressort tubulaire (9) détachable ou non détachable ainsi qu'un point de raccordement de système indicateur (10) détachable ou non détachable pour le système de mesure (4), lesquels sont réalisés, pour les connecteurs (3) et systèmes de mesure (4), avec une construction de raccordement unitaire et dimensionnés respectivement de façon toujours identique, peu importe que le manomètre à ressort tubulaire (1) soit raccordé radialement ou à l'arrière, qu'il soit ou non rempli de liquide et quelle que soit la grandeur du boîtier.
