PTFE Venting Membrane Applied in Humidity Sensors
Request a QuoteMS® PTFE Venting Membrane Applied in Humidity Sensors Description
Humidity sensor performance is dependent upon vent performance. Consistently high airflow and moisture vapor transmission rates are essential if sensors are to respond quickly to changes in ambient conditions. Rapid pressure equalization is essential for maintaining accurate readings and for preventing sensor failure that can cascade to component or system failure. High-airflow Membrane Solutions’ Vents facilitate rapid response in humidity sensors for higher performance and customer satisfaction.
Features & Benefits
- Superior airflow management / avoids condensation-related failures
- Reliable sensor operation / prevents over-pressurization or vacuum conditions within sensor
- An effective fluid barrier / blocks ingress of water and automotive solvents or oils
- Reliable protection from contaminants / blocks dust, dirt, debris
