Title
(EN) PNEUMATIC LEAK MEASUREMENT SYSTEM BASED ON ABSOLUTE PRESSURE DROP MEASUREMENT, WITH REFERENCE SAMPLE DIFFERENTIAL COMPENSATION
(FR) SYSTÈME DE MESURE DE FUITE PNEUMATIQUE BASÉ SUR UNE MESURE DE CHUTE DE PRESSION ABSOLUE, AVEC COMPENSATION DIFFÉRENTIELLE D'ÉCHANTILLON DE RÉFÉRENCE
Abstract
(EN)
The present invention specifically relates to the pneumatic and electronic application of a pneumatic leak meter based on absolute pressure drop measurement having the peculiarity of compensating for ambient variations such as ambient temperature and temperature of the measured part, as well as mechanical deformations of the component being tested caused by the pressure being applied.
(FR)
La présente invention concerne particulièrement l'application pneumatique et électronique d'un débitmètre pneumatique sur la base d'une mesure de chute de pression absolue ayant la particularité de compenser des variations ambiantes telles que la température ambiante et la température de la partie mesurée, ainsi que des déformations mécaniques du composant testé provoquées par la pression appliquée.
