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.

If you are using a pressure transducer (also known as a sensor) to measure liquid, gas or air pressure in a critical environment, OEM application or high-purity manufacturing process, you need to have confidence in the accuracy of your instrument. That confidence will be tested if there is an offset in the output of that instrument at zero and/or span. However, if you understand the reasons behind why offset can occur and what you can do to address it, your confidence will be restored. Ashcroft, an industry leader in pressure measurement instruments, has consistently demonstrated reliability and excellence in the field of pressure measurement instrumentation. That's why we are often asked to share our expertise and shed light on topics like this one. Read this article to learn how transducers measure pressure, possible causes of offset in the output of your sensor and what you can do to ensure your sensor is providing you with an accurate pressure measurement. You will also have the opportunity to deepen your knowledge through additional articles and resources available to you.

In the rapidly evolving landscape of hydrogen technology, pressure sensors play a pivotal role in ensuring the safety and efficiency of hydrogen transportation and storage. As the demand for hydrogen as a clean energy source grows, so does the need for advanced sensor technology that can accurately monitor and control hydrogen pressure in various applications. Ashcroft, in partnership with our parent company Nagano Keiki Co. LTD, has been designing advanced pressure sensors for the hydrogen market for 20 years. This extensive experience has resulted in several technology patents from Nagano Keiki, which enhance our ability to provide sensors specifically engineered with the right metallurgy for high-pressure applications. This puts Ashcroft in a unique position to guide our customers through the process of selecting the best types of pressure sensors for complex hydrogen systems. Read this article to explore key design challenges for pressure sensors used in hydrogen transportation, distribution and storage, as well as onboard engine applications. We will also review recent advancements that can enhance the safety and efficiency of your hydrogen applications.

When you need to measure air, gas or liquid in any industrial or OEM application, you will likely need to rely on a pressure transducer with sensing technology to keep your system running smoothly. However, process media, measurements and components can vary based on your industry and your specific application. The good news is that Ashcroft and its parent company Nagano Keiki Co. LTD (authorities in pressure measurement instrumentation) offer pressure transducers that can be customized to meet your requirements. Read this article to learn common reasons why companies want customization of their instruments, the features of Ashcroft pressure transducers that can be tailored to your specifications and how to get started. You will also find links to additional resources that will help you learn more about these instruments.

Working in cleanrooms, operating rooms and critical environments found in pharmaceutical and other industries requires you to maintain a positive pressure to prevent contaminants from entering these spaces. The pressure level necessary to keep these areas contaminant-free is typically between 0.01 to 0.15 inches of water differential. There are also negative pressure applications such as isolation rooms that require you to maintain pressures to similar levels. So, how exactly can you maintain such precise conditions to ensure these environments are safe for use? The solution lies in carefully choosing instruments specifically designed and calibrated for these critical environments, coupled with an understanding of the future calibration requirements necessary to guarantee precise and reliable readings over time. During the past eight years as a product manager overseeing the low-pressure sensor product line at Ashcroft, I’ve helped customers address this very issue with great success. In this article, you will learn about critical environments, reasons why instrument calibration is needed and how Ashcroft makes the process easier than traditional methods. You will also be directed to additional resources that can help answer other common questions about this topic.
