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.

When selecting pressure sensors for specific applications, it's important to understand the instrument's Ingress Protection (IP) rating. IP Ratings, which are also referred to as International Protection Ratings, determine the sensor's ability to withstand environmental factors such as moisture, dust and debris. These elements are commonly encountered in off-road vehicles, construction equipment, agricultural systems and other applications, and can significantly impact the performance and longevity of your pressure instruments. As a product manager at Ashcroft, a leading manufacturer of pressure and temperature instruments, I am often asked about which IP ratings are needed for instruments used in OEM applications. The answer depends on many factors. Read this article to learn more about the components of an IP rating, the factors that influence rating requirements and the applications covered in each category. When you are done reading, you will also find additional resources that may help you select the best IP-rated pressure sensor for your application.

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.
