Sensor Adhesive Vents Technology
How pressure equalization is achieved through structural design and material properties
Porous Membrane Technology
- The core component is a thin, porous membrane made of expanded polytetrafluoroethylene (ePTFE) or similar high-performance materials
- Features an interconnected network of microscopic pores that allow air molecules to pass while blocking liquids and contaminants
- Acts as a passage for air movement between the inside and outside of sensor housings
- Gradually reduces pressure differences until equilibrium is reached
Dynamic Pressure Response
- Responds dynamically to pressure changes without requiring manual intervention
- When internal pressure rises, expanded air pushes against the membrane, releasing excess pressure
- When external pressure is higher, external air is drawn into the housing through the same pores
- Automatic, bidirectional air flow prevents damaging pressure differences
Adhesive Backing Functionality
- Creates a secure, airtight bond between the vent and sensor housing surface
- Prevents air leakage through gaps around the vent's edges
- Ensures all pressure adjustment occurs exclusively through the porous membrane
- Maintains consistent performance even in environments with vibration or temperature variations
Environmental Adaptation
- Design optimized to adapt to different environmental conditions affecting pressure
- Some vents include a protective layer to shield the membrane from harsh substances
- Protection ensures the membrane remains unclogged and functional
- Maintains pressure equalization capability even in challenging settings
