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.

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.

Pressure transducers are important instruments that are used to measure air, gas or liquid pressure in many industrial applications. They work by measuring pressure at various stages of a process and converting the measurement into an electrical signal, which is used to monitor and control the overall system. Ashcroft has been making pressure transducers for decades and one question we are often asked is whether these instruments can be installed in any orientation. While the short answer is “yes, they can,” there are factors to consider before you install your transducers. Read this article to learn how transducers work, the effect that changing the orientation may have on the instrument’s accuracy and how position errors can be fixed. You will also be directed to additional resources that can help answer other common questions about pressure transducers.

According to the Environmental Protection Agency (EPA), groundwater serves as a crucial resource for half of the U.S. population. Reliance on this vital natural resource is especially significant in regions with scarce rainfall, limited surface water availability, or high agricultural demands and population. As a leading manufacturer of pressure and temperature instrumentation, Ashcroft understands the challenges of protecting this vital resource. In this article, you will learn about submersible pressure transmitters and how they are used to monitor water levels and provide essential information to water management personnel. You will also see examples of four common applications where submersibles are used and some challenges these instruments may encounter while in use. When you are done reading, you will find additional, related resources that may be of interest when you are ready to go beyond the basics of this topic.

Measuring very low-pressure in controlled environments like data centers, isolation rooms, labs, and operating rooms, for example, is challenging because they must maintain a very specific and very controlled atmosphere. If these environments are compromised in any way, it puts the people and the equipment you are protecting at risk. That's why you must ensure your pressure measurement instrumentation meets the specified guidelines for accuracy and reliability. As a product manager at Ashcroft, I have 26 years of industry experience, including the past eight years working exclusively on low-pressure sensing technology. In this article, you will see how we define 'very low' pressure, see examples of controlled environments where low-pressure measurements are required, and learn how pressure is measured in these applications. You will also gain a better understanding of the impact temperature has on pressure measurement and what to look for in a pressure measurement instrument to ensure your controlled environment stays secure. When you are done reading, you will also be directed to additional articles and resources that may be of interest for other questions you may have.

Chemical vapor deposition (CVD) is a process used to create highly advanced, field-proven, thin film technology for pressure sensors that are used in mid- to high-pressure applications. These sensors are designed to deliver consistently accurate, reliable and repeatable pressure measurements under some of the most difficult conditions. If you are an Original Equipment Manufacturer (OEM), you know that your operations are among the most rugged in any industry. As such, you require instrumentation that is both consistently accurate and able to meet the shock, vibration, temperature and high cycle demands of your applications. As a recognized leader in pressure and temperature instrumentation, Ashcroft pressure transducers offer OEM customers everything they need in a high-quality pressure transducer. Our CVD-based sensors are produced in Japan by our parent company, Nagano Keiki, and are used in many of our pressure sensors, especially those needed for OEMs. In this article, you will learn how CVD technology works in the manufacturing process, applications where you will find this technology and the benefits it offers to OEM manufacturers and others who use it. When you are done reading, you will see other related resources that will help you learn more about the pressure instruments that incorporate CVD technology and the applications where they are used.
