Pressure Transducer Case Vent Rupturable Membrane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard pressure transducers can suffer catastrophic failure due to internal pressure buildup from leaks or high external temperatures, leading to potential damage from pressure rupture or component ignition.
Innovation Solution
A sealed transducer assembly with a vent bore and a rupturable membrane that maintains a seal within a specified pressure differential range, rupturing and venting pressure when the differential exceeds a certain level to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transducer case is sealed to prevent leaks, then reliability is improved, but pressure buildup from internal leaks or high temperatures can cause catastrophic failure
Solution Approach 1:
A vent bore is pre-configured in the transducer case, sealed by a rupturable membrane during manufacturing. This preliminary setup allows the system to maintain hermetic sealing under normal conditions while having a pre-planned pressure relief path activated only when necessary, preventing catastrophic failure from pressure buildup.
2Object-affected harmful factors
If a vent bore is added to relieve pressure, then pressure relief capability is improved, but the hermetic seal is compromised
Solution Approach 1:
A rupturable membrane is introduced as an intermediary element between the sealed transducer case and the vent bore. This membrane maintains the hermetic seal under normal operating conditions while providing a controlled failure mode that relieves pressure when the differential exceeds a predetermined threshold, thus mediating between seal integrity and pressure relief requirements.
3Strength
If the transducer is designed to withstand high pressure, then strength is improved, but the device complexity increases
Solution Approach 1:
The transducer case is segmented into functional zones: a sealed internal portion housing the transducer, and an external portion with a vent bore. The rupturable membrane creates a distinct separation that allows the case to be designed for strength without requiring the entire structure to withstand maximum pressure differentials, as the membrane fails first to relieve excessive pressure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents catastrophic failure by safely relieving internal pressure, maintaining a hermetic seal until the membrane ruptures, thereby protecting the transducer and surrounding components from damage.
Implementation Method 1
the rupturable membrane may be configured to maintain a seal within the internal portion of the transducer assembly, for a first range of a pressure differential between the internal portion of the transducer assembly and the external portion of the transducer assembly
Implementation Method 2
The rupturable membrane may be configured to rupture and vent pressure through the vent bore when the pressure differential exceeds the first range

AI summary
Certain implementations of the disclosed technology may include systems, methods, and sealed transducer assembly with a pressure relief vent. In certain implementations, a transducer assembly is provided having a vent bore and a rupturable membrane sealing the vent bore. The vent bore may extend from an internal portion of the transducer assembly to an external portion of the transducer assembly. The rupturable membrane is configured to maintain a seal within the internal portion of the transducer assembly for a first range of a pressure differential between the internal portion of the transducer assembly and the external portion of the transducer assembly, and rupture and vent pressure through the vent bore when the pressure differential exceeds the first range.
