Why Is Leak-Free Pressure Measurement Crucial for Hydrogen?
Due to the small molecular size of hydrogen, there is a high risk of permeation, turning even the smallest leak into a critical issue. Especially in high-pressure systems, leaks represent a significant safety risk. Additionally, high pressures and rapid load changes typical in H2 applications require extremely robust and reliable measurement components to ensure long-term system integrity.
What Engineers Need to Consider for H2 Pressure Sensors
- Proven material resistance and proven H2 suitability of pressure sensors are fundamental to preventing material embrittlement.
- A hermetically sealed, fully welded sensor design is essential to prevent leaks. Proof of tightness, for example through a 100% helium leak test, provides additional confidence.
- Furthermore, sensors must cover the relevant pressure and measuring ranges of the application, exhibit high accuracy as well as long-term stability, and be designed for the specific operating temperature range.
