A sensor device with a robust outer capsule design, comprising a first and second capsule portion, a mounting bracket, pressure sensors, and a Hall Effect sensor, capable of withstanding pressures up to 100 bar, formed from fiber-reinforced polymer plastic, and equipped with a power source and data storage for fluid and conduit property measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the sensor device uses a conventional capsule design without a mounting bracket, then the device complexity is reduced, but the pressure resistivity and structural integrity under high fluid pressure deteriorate
Solution Approach 1:
The capsule is divided into two separate portions (first capsule portion and second capsule portion) that are joined together. This segmentation allows each portion to be optimized for specific functions while distributing the mechanical stress under pressure, thereby improving pressure resistivity without excessive complexity
Solution Approach 2:
A mounting bracket is introduced as an intermediary component between the two capsule portions. This bracket provides structural support and pressure distribution, enabling the capsule to withstand high fluid pressures while maintaining a manageable structural complexity
2Strength
If the outer capsule is designed to withstand high pressures up to 100 bar, then the pressure resistivity is improved, but the manufacturing complexity and material requirements worsen
Solution Approach 1:
The outer capsule is constructed using composite materials that combine the strengths of different materials to achieve high pressure resistance (up to 100 bar) while maintaining manufacturability. This allows the capsule to meet stringent pressure requirements without requiring overly complex manufacturing processes
3Measurement precision
If the sensor device includes a mounting bracket with hollow annular member holding the pressure sensor, then the measurement precision of fluid pressure is improved, but the device complexity increases
Solution Approach 1:
The hollow annular member of the mounting bracket is designed with specific local structural qualities that concentrate and transmit pressure forces directly to the pressure sensor. This localized structural optimization improves measurement precision by ensuring accurate force transmission while keeping the overall bracket design relatively simple

AI summary
There is provided a sensor device for measuring fluid and fluid conduit properties, and a method for activating the sensor device. The sensor device comprises an outer capsule for providing fluid-tight containment to an interior compartment of the sensor device in a closed position. The outer capsule comprises a first capsule portion and a second capsule portion. An aperture is located in the second capsule portion and fluidly connects the inner compartment to an exterior of the outer capsule. A mounting bracket is disposed within the inner compartment, the mounting bracket connects the first capsule portion to the second capsule portion and provides structural integrity and pressure resistivity for the outer capsule. At least one pressure sensor is constrained between the mounting bracket and an inner surface of the second capsule portion and is aligned with the aperture of the second capsule portion.
