When measuring pressure in challenging environments involving extreme temperatures, your instrument must perform accurately and reliably. Temperature exposure can come from many sources, including the process media and the ambient temperature surrounding the sensor. Each affects the transducer differently, but media temperature has the most direct impact because it acts on the sensing diaphragm and internal components. As media temperature rises or falls, it can distort readings, shorten sensor life or even damage components. With more than 175 years of pressure and temperature measurement expertise, Ashcroft is recognized as an industry authority in helping customers maintain reliable measurement in even the harshest environments. In this article, you’ll learn how process media temperature can impact pressure transducer performance, what causes output changes and how to minimize errors through proper design and installation. Understanding this information will help ensure you protect your instruments from performance drift or premature failure.

If you work in oil and gas, chemical and petrochemical, or any other industry that involves high heat, your challenge is to find instruments that are designed to withstand the extreme temperature conditions of the environment and your process media. For example, pressure gauges have specific temperature ranges. If your application goes beyond the instrument's limits, you may need to add an accessory to maintain the integrity and accuracy of your gauge. As the accessories product leader at Ashcroft, part of my job involves educating customers and distributors about the options available to keep their systems running safely and efficiently. In this article, you will learn how to protect your pressure gauges from getting damaged in harsh applications. You will also see links to additional articles and resources that will help deepen your knowledge of pressure gauges and the accessories that support them.

Pressure gauge accessories like snubbers, dampeners, capillaries, pressure-limiting valves, and siphons play an important role in keeping your processes running safely and efficiently. However, while these devices help ensure your pressure instruments maintain optimal performance in the most challenging applications, there is an underlying concern about their potential impact on pressure measurement accuracy. As the product manager for pressure gauges and accessories at Ashcroft - a leader in pressure and temperature instrumentation, I am often asked for reassurance that these products don't interfere with gauge performance. In this article, you will learn about the factors that can affect pressure measurement accuracy, and the accessories that help, not hinder, instrument performance.

Isolation rings are very effective devices that protect pressure instruments from contaminant clogging and corrosion in several industries. However, there are certain circumstances where alternate methods of instrument isolation are recommended. As a global leader in pressure and temperature instrumentation, customers rely on the depth and breadth of our experience to educate and guide them through the process of finding the best solutions for their specific needs. In this article, you will learn why isolation rings are a good option for several very specific types of applications, but would not be recommended for others. As you read, look for links to resources that can help provide additional information to deepen your knowledge on this particular topic.

Keeping pressure measurement instruments from becoming damaged in harsh environments is a challenge in many industries, including water/wastewater. Diaphragm seals play a vital role in these applications by creating a leak-tight and corrosion-resistant barrier between a pressure instrument and your process. For many, a flanged diaphragm seal connection is a great choice because it provides a convenient way to attach instrumentation directly onto flanged process piping without having to use threaded connections. But proper installation of these seals is the key to getting the most protection. Ashcroft is a recognized global leader in pressure and temperature instrumentation and uses our decades of experience to educate and guide customers to the solutions that best meet the challenge at hand. In this article, you will learn a bit about flanged diaphragm seals, the basic principles of torque and best practices for installing a flanged diaphragm seal in your process. When you are done reading, we will also share additional resources that may be beneficial to you.
