This article was originally published on October 2, 2023, and updated on October 14, 2024. The number of industries that rely on pressure measurement equipment is expansive. The list includes manufacturing, water/wastewater, hydraulics, food and beverage, medical, and pharmaceutical, among others. If you are new to any of these markets, you need to understand the importance of monitoring and maintaining appropriate levels of pressure in the critical processes in your industry. Accurate measurement of pressure in these processes is essential for ensuring safety, control and process efficiency. However, achieving these goals requires periodic instrument calibration. With more than 12 years of specialization in precision instruments, I have witnessed first-hand the consequences of neglecting calibration. As a follow-up to my blog titled, How to Check the Calibration of a Pressure Gauge, this article examines in more detail the circumstances that necessitate this important process, focuses on the three most critical factors of calibration and discusses the considerations associated with each factor. When you finish reading, you will have a solid foundation of knowledge regarding pressure instrument calibration and be ready to dig deeper into the topic with the additional resources provided for your reference.

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.

In applications involving conductive fluids such as tap water, seawater, ammonia and condensation from air and gases, safeguarding pressure instruments against galvanic corrosion is a critical concern. The corrosive nature of these systems can significantly compromise the functionality and longevity of your instrumentation, underscoring the importance of selecting the most appropriate options for your specific requirements. Typically, people focus on media compatibility as it relates to the wetted materials of the individual components that will be used in a system such as pressure instruments. However, it is also critical to identify potential areas of galvanic corrosion throughout the entire system and only use materials that are corrosive-resistant and compatible with galvanic conditions. Ashcroft has a long and successful history in pressure and temperature instrumentation, including those used in harsh applications such as saltwater and chemical environments. Read this article to better understand galvanic corrosion, where and how it occurs, and why media and material compatibility are so important when selecting the best pressure measurement solution for water-based applications. You will also be directed to additional resources that can help you take the next step in your instrument-purchasing journey.

A 4-20 mA analog output is a universally recognized industry standard for relaying electrical signals (as currents) over long distances. For example, many sensing instruments such as pressure transmitters and transducers use a 4-20 mA output as a simple and reliable method to convey information from the field to a system control room. If you want to learn more about this type of output, and the benefits of the 2-wire connection option vs. a 3-wire option, you've come to the right place. I have been a product leader at Ashcroft for almost two decades and have extensive experience in pressure and temperature measurement. During that time, I've been asked a lot of questions about how things work and the benefits of selecting one measurement device over another. We created our Understanding the Basics series to give those who are new to the industry a framework of information to use as a valuable point of reference when needed. In this article, you will learn about 4-20 mA analog outputs, including where they are used, how they work, and the advantages and challenges of using the 2-wire vs. a 3-wire in your application. When you're finished, you'll know if this type of output is right for you.

Whether you are measuring low-pressure airflow in a critical environment, high-pressure mobile hydraulics in OEM applications, or even ultra-high purity gases in semiconductor manufacturing, you are likely relying on a pressure transducer to keep your system running safely and efficiently.
