As hydrogen gains momentum as a clean energy solution, pressure sensors play a critical role in ensuring the safety, efficiency, and reliability of hydrogen systems — from production to distribution. However, hydrogen’s unique properties, including embrittlement and permeation risks, present serious challenges for conventional sensing technologies.
This white paper, brought to you by Druck, a Baker Hughes Business, explores the key design considerations for hydrogen pressure sensors. It covers the impact of hydrogen on sensor materials, discusses evolving certification standards like UN ECE R134, and highlights advanced solutions such as Druck’s barrier-coated diaphragm and TERPS technology — engineered for performance in the most demanding hydrogen environments.
