How to test the performance of sensor ePTFE vents - Wuxi Sinceriend New Material Technology Co., Ltd.

Ventilation Efficiency Testing

Assessing ventilation efficiency requires placing the ePTFE vent in a controlled test environment that simulates real-world conditions. Measure the air flow rate through the vent under steady pressure, ensuring the test setup eliminates external interference that could skew results.

A qualified vent should allow consistent air circulation without excessive resistance.
Inadequate ventilation can lead to internal moisture accumulation and sensor malfunction.
Testing focuses on preventing pressure buildup inside sensor housings and avoiding fogging or damage.

Waterproof & Dustproof Performance Testing

These are primary protective functions of sensor ePTFE vents, requiring rigorous validation.

Waterproof Testing: Expose the vent to water exposure that mimics its intended use, checking for any water penetration after the test period.
Dustproof Testing: Subject the vent to fine particulate matter in a controlled chamber, then inspect whether dust particles have passed through to the sensor side.

Long-Term Stability & Environmental Adaptability

This testing ensures the vent maintains performance under the conditions it will encounter in service.

Expose the vent to varying environmental conditions such as temperature fluctuations and chemical exposure, consistent with the target industries.
After prolonged exposure, re-evaluate its ventilation, waterproof, and dustproof capabilities to ensure no degradation.

Structural Integrity Verification

The final verification step ensures the vent remains intact and functional throughout its lifecycle.

Confirm the vent's physical structure remains intact after all environmental and performance tests.
Verify continued functional performance, ensuring reliable protection for sensors over extended use.

A systematic testing approach covering these core functional requirements ensures ePTFE vents can reliably protect sensors and maintain stable operation in their intended applications.
