As industries move to adopt hydrogen as a clean energy source, the demand for robust pressure sensing technology has never been greater. But hydrogen introduces unique challenges. For example, many hydrogen applications have processes that can cause hydrogen ion diffusion. This can lead to hydrogen permeation and embrittlement, which can cause premature failure of your measurement instruments. Ashcroft is a leading authority in pressure and temperature instrumentation, with decades of experience designing solutions that meet the unique demands of hydrogen environments. We wrote this article in response to a question that came into our help desk. Read on to learn about hydrogen permeation and hydrogen embrittlement, why they matter in hydrogen applications and how several Ashcroft® pressure transducers are uniquely engineered to mitigate each of these issues. You will also find additional resources that may address other questions you may have about hydrogen applications and selecting the right instrumentation for your system.
