iTHERM ModuLine thermometers for a wide range of hydrogen applications

Temperature control plays a vital role in hydrogen production, ensuring efficiency and safety across all stages—from energy generation and electrolysis to compression and storage. The process involves demanding conditions such as high pressures, hazardous areas, and strict safety standards like SIL compliance. Reliable temperature measurement technology must withstand pressures up to 500 bar and operate safely in explosive environments. Standardized solutions with high flexibility are essential to meet diverse application needs.

With its modular and scalable design, the iTHERM ModuLine portfolio provides a reliable and future-proof temperature measurement solution for hydrogen production. Whether used in standard applications or under extreme conditions involving high pressures, hazardous areas, and strict safety requirements, the sensors deliver consistent performance and compliance. The portfolio combines pressure resistance up to 500 bar, SIL and Ex certifications, and high flexibility to meet diverse process needs. This ensures safe, efficient, and cost-effective operation across the entire hydrogen value chain—supporting the industry’s progress toward a sustainable energy future.

Hydrogen production is a cornerstone of the global energy transition and essential for meeting long-term climate targets such as NetZero 2050. To ensure optimal efficiency and environmental sustainability, precise and reliable process instrumentation is required throughout the entire value chain—from renewable energy generation and electrolysis to compression, storage, and utilization. Temperature is a critical control parameter in nearly all stages of hydrogen production and must be continuously monitored and regulated. In electrolyzer systems, temperature sensors must comply with SIL (Safety Integrity Level) standards and be certified for use in hazardous areas, withstanding pressures up to 40 bar. In subsequent compression stages, the process pressure can rise significantly, reaching up to 200 bar, demanding robust and high-performance measurement solutions.
