Sensors for the hydrogen economy
Level and pressure instrumentation for all measuring tasks
The production, storage and efficient transport will all be decisive factors in the hydrogen economy of the future. Whether hydrogen is in liquid or gaseous form, or has been converted into ammonia, methane or e-fuels: VEGA sensors ensure that all hydrogen processes operate safely with the correct quantities and pressures.

SENSORS FOR THE HYDROGEN ECONOMY
Level sensors for the hydrogen industryVEGA’s level sensors reliably measure the level in hydrogen tanks and containers and warn of overfilling, underfilling or leakage. They deliver reliable measurement results, even when operating with small measurement ranges. Tank internals do not impair the accuracy of the readings. |

Pressure sensors for the hydrogen industryVEGA’s pressure sensors measure the pressure of hydrogen gas in pipelines, containers, tanks and other handling systems. They ensure long-term stability measurements and are especially easy to set up and put into operation. |
Point level sensors for the hydrogen industryVEGA’s point level sensors detect the limit level in hydrogen tanks and containers. They ensure maximum reliability and safety in all hydrogen applications. |
Special requirements
💧 Hydrogen is the smallest atomic element and is gaseous under normal conditions. It only becomes liquid at temperatures at or below -253 °C. Hydrogen also has the highest diffusion density of all gases.
These properties place special demands on the materials used for suitable measuring instruments.
- Diffusion: If hydrogen penetrates a material, such as a metal or other wetted construction parts, it can be damaged over time – this can permanently alter the performance of a measuring instrument.
- Embrittlement: Hydrogen atoms can penetrate the atomic structure of a material and significantly worsen its mechanical properties, and it becomes brittle.
VEGA sensors deliver precise and reliable measuring results despite these challenges. Resistant materials, diffusion-tight process fittings, oil-free ceramic measuring cells and sensors with gold or gold-rhodium coatings, ensure long-term functionality.
Golden protection
🥇 Gold: A gold coating is particularly suitable when hydrogen is present in a pure gaseous form, i.e. as dry hydrogen. At a thickness of around 25 µm, it resists diffusion very effectively.
🥇 Gold-Rhodium: When hydrogen is dissolved in aqueous solutions, the challenges for the diffusion barrier are even greater. A thin layer of rhodium covers the gold-coated metallic diaphragm. It not only protects the soft gold coating, but also acts as a catalyst, significantly reducing the effects of diffusion.
