Industrial Sensors Waterproof Breathable Membrane
Industrial sensors — pressure transmitters, flow meters, gas detectors, and PLC-mounted detectors — sit inside sealed metal and plastic enclosures that face oil mist, solvent vapor, cyclic heat, and outdoor dust. Our ePTFE waterproof breathable membrane lets each enclosure breathe and equalize pressure without letting contaminants reach the sensitive element inside.

Product Overview
The microporous structure of ePTFE allows air to pass freely while blocking liquid water, dust and industrial contaminants. It effectively balances internal and external pressure, preventing condensation inside sealed sensor housings and ensuring long-term stable operation.
Core Advantages
- IP67/IP68 waterproof and dustproof protection for industrial environments
- Stable air permeability to prevent pressure imbalance in sealed enclosures
- Resistant to oil mist, weak acids and industrial chemical exposure
- Performs under wide temperature range for harsh factory conditions
- Custom die-cut sizes available for different sensor designs
Main Applications
- Industrial automation sensors
- Environmental monitoring equipment
- Factory control and detection systems
- Hydraulic and pneumatic sensor modules
- Outdoor industrial monitoring devices
What to Specify for an Industrial Sensor Vent
- Chemical compatibility: confirm the membrane resists the oils, coolants, or solvents present in the enclosure
- Temperature cycling: ePTFE stays stable from −40 °C to +260 °C through repeated heat swings
- Enclosure volume vs breathability: match ml/min to housing size so pressure equalizes quickly
- Ingress rating: target IP67/IP68 for washdown or outdoor installations
- Acoustic path: for sensors with a mic port, use acoustic-transparent ePTFE to avoid sound loss
