Universal Flange-Set for Pressure Transducer Adapter Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pressure difference measuring transducers with membranes arranged in a plane next to each other cannot be directly connected to process connections designed for transducers with diametrically opposite membranes due to different process connection geometries, requiring adapters that increase costs and assembly effort and may not fit in all locations.
Innovation Solution
A flange-set with specifically designed first process connections that allow pressure difference measuring transducers with membranes on opposite sides to be mounted on process connections with a different geometry, eliminating the need for adapters and enhancing vibration resistance by integrating securing means and ventilation features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapters are used to connect transducers with opposite-side membranes to process connections designed for planar membranes, then compatibility is improved, but device complexity and assembly effort increase
Solution Approach 1:
The flange-set is designed with a universal geometry that can connect to both process connections designed for planar membranes and those for opposite-side membranes. The flange geometry includes specifically positioned pressure duct connection regions that accommodate both connection types, eliminating the need for different adapters for different transducer configurations.
2Adaptability or versatility
If adapters are used to connect transducers with opposite-side membranes to process connections designed for planar membranes, then compatibility is improved, but costs increase
Solution Approach 1:
The flange-set provides a universal connection solution that eliminates the need for multiple specialized adapters. By designing the flange with adaptable pressure duct connection regions, a single component design can serve multiple connection geometries, reducing manufacturing costs through standardization.
3Adaptability or versatility
If adapters are used for connection, then compatibility is improved, but additional seals are required increasing assembly complexity
Solution Approach 1:
The flange-set integrates the sealing function directly into the flange structure itself. The flange geometry includes built-in sealing surfaces and pressure duct connection regions that maintain sealing integrity without requiring separate adapter components with additional seals. This merging of connection and sealing functions reduces the total number of sealing elements required.

AI summary
A flange-set for a pressure difference measuring transducer with two flanges mountable on external sides of a measuring mechanism of the pressure difference measuring transducer lying opposite one another and containing membranes to be loaded with pressures, as well as a pressure difference measuring transducer equipped with the flange-set. Each of the flanges comprises: a wall, which in the mounted state covers one of the two membranes of the measuring mechanism and encloses a pressure chamber bordering on such membrane. Arranged on a first side of the wall is a first process connection, which includes a pressure duct connection region, in which opens a pressure duct extending through the flange to the pressure chamber. The first process connections are embodied in such a manner that a pressure difference measuring transducer equipped with the flange-set is mountable and connectable via the first process connections (without interpositioning of an adapter) on a process connection, which has a first process connection geometry designed for the connection and mounting of pressure difference measuring transducers with measuring mechanisms having membranes arranged next to one another in a plane.
