1Reliability
If a conventional insulating fluid monitoring block is used, then pressure and density monitoring can be performed, but retrofitting into existing structures is difficult and integration complexity increases
Solution Approach 1:
The monitoring block is divided into separate functional modules: a supporting body with integrated fluid channels, and separate sensor elements (pressure sensor, density sensor) that can be independently installed into cutouts on the supporting body. This segmentation allows the supporting body to be retrofitted independently while sensors can be added or replaced separately, significantly improving retrofitting ease.
Solution Approach 2:
Sensor elements are nested within cutouts on the supporting body, with the active areas of the sensors positioned to face each other across the cutout. This nesting arrangement allows multiple sensors to be integrated into a compact configuration on the supporting body, maintaining monitoring capability while simplifying the overall integration process.
2Ease of operation
If sensor elements are integrated into the supporting body, then retrofitting becomes easier, but manufacturing precision requirements increase
Solution Approach 1:
The supporting body is pre-manufactured with precisely positioned cutouts at predetermined locations where sensors will be installed. This preliminary preparation of the supporting body structure ensures that when sensors are later installed during retrofitting, they automatically achieve the required positioning precision without requiring complex alignment procedures during installation.
Solution Approach 2:
The supporting body features localized cutouts with specific geometries designed for particular sensor types. Each cutout is precisely shaped and positioned to accommodate its intended sensor, ensuring proper alignment and sealing. This localized customization allows high manufacturing precision to be achieved only where needed, rather than requiring precision throughout the entire structure.
