PROCESS INSULATING MEMBRANE ASSEMBLY FOR THE METAL PROCESS SEALING Russian patent published in 2018 - IPC G01L13/02 

FIELD: process devices.

SUBSTANCE: inventions relate to the field of process devices, such as process fluid pressure transducers. Claimed group of inventions includes the process fluid pressure transducer, insulating membrane assembly unit for the process fluid pressure transducer and the process fluid pressure transducer assembly formation method. Wherein the process fluid pressure transducer comprises: sensor housing including: pressure sensor and electronic components connected to the pressure sensor and configured to receive pressure indication from the pressure sensor, and at least one process fluid insulation assembly in fluid communication with the pressure sensor and configured to receive the process fluid, at that, at least one process fluid insulation assembly includes welded to the welded ring insulating membrane, wherein the weld ring has sealing surface on the first side adapted to contact the metal sealing ring and the weld portion welded to the sensor housing on the second side, wherein at least portion of the said weld portion is positioned directly above the said sealing surface so, that the sealing surface and the said weld portion are substantially aligned with each other.

EFFECT: technical result consists in provision of the process insulating membrane assembly, which retains all advantages of the metal seals with less disadvantages, will represent improvement in the process insulating membrane assemblies for applications with the high-pressure process fluid medium.
