At ESI Technology, we continue to lead the way in advanced pressure measurement solutions for emerging clean energy industries. As hydrogen becomes a key element in the transition toward a sustainable energy future, the demand for safe, accurate, and reliable pressure monitoring is greater than ever. Our HI6200H Compact Hydrogen Pressure Transmitter has been specifically developed to meet the unique challenges of hydrogen applications — combining exceptional performance, robust design, and cutting-edge technology in a compact form.

Engineered for Hydrogen Compatibility

Hydrogen is the smallest and lightest molecule in the periodic table. Its unique properties present specific challenges for pressure instrumentation, including the risk of hydrogen permeation, embrittlement, and sensor degradation. The HI6200H Compact Hydrogen Pressure Transmitter has been engineered from the ground up to overcome these challenges.

Each unit features a silicon-on-sapphire sensor made from specialist titanium alloy proven to resist hydrogen diffusion. This ensures long-term stability, accuracy, and safety, even in demanding environments. The transmitter is designed for full compatibility with pure hydrogen and hydrogen blends, making it ideal for hydrogen refuelling stations, storage systems, fuel cells, and industrial hydrogen processes.

Compact Design, Powerful Performance

The HI6200H Compact Hydrogen Pressure Transmitter delivers outstanding performance within a remarkably small housing. Its compact footprint allows for easy integration into confined systems without compromising on accuracy or durability.

With pressure ranges up to 5,000 bar, the HI6200H is capable of measuring even the most demanding hydrogen applications, from low-pressure monitoring to high-pressure refuelling operations. Its robust design ensures dependable performance in dynamic and high-vibration environments — a critical factor in hydrogen energy infrastructure and transport solutions.

High Accuracy and Fast Response

Accurate pressure measurement is essential for maintaining system efficiency and safety in hydrogen applications. The HI6200H Compact Hydrogen Pressure Transmitter offers high accuracy up to ±0.1% FS, ensuring precise and repeatable readings. The sensor’s digital processing electronics provide rapid signal transmission, enabling real-time system monitoring and control.

Whether used for safety-critical applications or process optimisation, this transmitter ensures that operators can rely on continuous, accurate data for efficient system management.

Built for Harsh Environments

Hydrogen production, storage, and distribution environments can be harsh — with extreme temperatures, vibration, and exposure to the elements. The HI6200H Compact Hydrogen Pressure Transmitter has been rigorously tested to withstand these conditions.

With ingress protection up to IP67, it provides reliable operation even in challenging outdoor or mobile applications. The transmitter’s all-welded construction eliminates potential leak paths, ensuring a long operational life and reduced maintenance requirements.

Designed and Manufactured in the UK

Like all our products, the HI6200H is designed, manufactured, and tested in the UK at ESI Technology’s ISO 9001-certified facility. Every transmitter undergoes strict quality assurance and calibration to guarantee performance consistency.
