Abstract: An isolator diaphragm (13) is formed and connected to a support member (16A) so it will withstand periodic high pressure cleaning. The isolator diaphragm (13) has a peripheral wall portion bonded to a planar support (26) surface and is formed to have a center region (38). The peripheral wall and center region (38) are joined by a conical, inclined wall (28) bounding the center region (38). The support member (16A) has a correspondingly shaped recess (32) with an inclined annular wall (30) that supports the conical wall (28) of the diaphragm. The primary diaphragm flexure point of the center portion (38) of the diaphragm (13) is moved away from the perimeter of the diaphragm, to adjacent the junction of the inclined wall (28) and the center region (38).

Abstract: An isolator (10) for use in pressure transmitters comprises an isolating diaphragm (14) that is thin, and made of a suitable corrosion resistant metal, such as tantalum, and which must be anchored to an isolator housing (12) made of a substantially different metal such as stainless steel. The present invention relates to securing a support ring (24) of the same metal as the diaphragm (14) surrounding the cavity (15) formed for the isolator fluid, preforming a thin metal diaphragm (14) made of the selected material, and then welding the diaphragm (14) and a ring (34) overlaying the diaphragm directly to the support ring (24).

Abstract: Un isolateur (10) utilisé dans des émetteurs de pression comprend un diaphragme isolant (14) qui est mince, est constitué d'un métal approprié résistant à la corrosion, tel que le tantale, et qui doit être ancré sur un boîtier (12) d'isolateur constitué d'un métal sensiblement différent tel que l'acier inox. L'invention concerne la fixation d'une bague de support (24) constituée du même métal que le diaphragme (14) entourant la cavité (15) formée pour le fluide de l'isolateur, l'obtention d'un diaphragme en métal mince (14) constitué du matériau sélectionné, puis le soudage du diaphragme (14) et une bague (34) reposant sur le diaphragme (14) directement à la bague de support (24).
