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.

Hydrofluoric acid (HF) is well known for its aggressive and hazardous characteristics. That’s why selecting material for these applications is important for ensuring the safety and performance of your instruments and your operation. Ashcroft is a recognized leader in pressure measurement instrumentation and understands the unique challenges of hydrofluoric acid (HF). Read this article to learn about stress corrosion cracking, the comparative properties of Monel® 400 and Monel® K-500, their performance in HF environments, and considerations for using these or alternative materials in applications where corrosion resistance is critical.

There are many different styles of thermowells, so depending on what you need, the cost for these instruments can be as low as $15 or as high as $5,000. With such a broad price range, selecting the right one for your application can be difficult. Ashcroft is a leader in pressure and temperature instrumentation. In my role as an engineer and product leader at the company, I have insight into the factors that can affect a thermowell's cost and what to consider before you place an order. Read this article to learn about the price ranges of thermowells and the key cost drivers, including product design, materials, testing requirements and more. You will also receive links to additional resources to help deepen your knowledge about the temperature instruments we offer. Please note: the costs represented in this article depend on the material, the requirements/tests needed, and the process conditions involved.

Ensuring the reliability and safety of pressure measurement instruments is important in any application, especially when you are dealing with challenging environmental conditions. Rating systems including the Ingress Protection (IP) and National Electrical Manufacturers Association (NEMA) were created to level the playing field for manufacturers by providing a standardized measure of an instrument's ability to withstand environmental challenges. Understanding these rating systems can help you select the right equipment for your operational needs, ensuring instrument durability and safety. With close to two centuries of experience as a global leader in pressure and temperature instrumentation, Ashcroft can help you understand why these ratings are important and what to look for when selecting pressure instruments for certain applications. When you're done reading, we will also share additional information that can help guide your selection process.

No gauge can stay completely accurate forever. That's why it is important to regularly check the instrument's accuracy to ensure it continues to provide correct readings for your application. If you don’t check, inaccurate pressure readings can cause your equipment to malfunction and break down or, even worse, result in injury to workers. All of these scenarios can impact system efficiencies and lead to downtime for your business. Ashcroft has been a leading manufacturer of pressure gauges since 1952, so the question relating to calibration frequency is one we encounter a lot. While there are no universally defined requirements for calibration, I can provide insights that can help you determine what may be the most appropriate times to check your pressure gauge accuracy.

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.
