The GS4200H hydrogen pressure transmitter has been developed to provide accurate and dependable pressure measurement for the growing range of hydrogen-based applications. Designed for use in demanding environments, it combines ESI’s advanced Silicon-on-Sapphire (SOS) sensor technology with hydrogen-compatible materials to deliver exceptional stability, reliability, and long-term performance.

Hydrogen presents unique challenges for pressure measurement due to its small molecular size and potential effects on materials. The GS4200H has been specifically engineered to overcome these challenges, incorporating a titanium alloy sensing element and wetted parts selected for hydrogen compatibility. This ensures reliable operation while maintaining high levels of accuracy and repeatability throughout the transmitter’s service life.

Suitable for applications including hydrogen production, storage, distribution, fuel cell systems, industrial processes, and energy infrastructure, the GS4200H provides a versatile solution for measuring pressures from vacuum up to 1,500 bar. Its robust construction and proven SOS technology make it ideal for applications where dependable pressure data is essential.

The GS4200H is tested for hydrogen compatibility in accordance with ISO 11114-4:2017 and meets the requirements of European hydrogen regulations EC 79/2009 and EU 406/2010. Optional ATEX and IECEx approvals are available for hazardous area applications, while DNV certification options support use in demanding marine and offshore environments.

Manufactured by ESI Technology, the GS4200H combines specialist hydrogen expertise with proven pressure measurement technology, providing engineers with a safe, durable, and accurate solution for the future of hydrogen energy.
