In many process industries, sudden pressure surges from water hammer, valve closures or equipment malfunctions can cause overpressure events that damage pressure gauges and lead to equipment failure and costly downtime. To reduce this risk, many systems rely on external pressure limiting valves (PLVs), which increase installation complexity and create potential leak paths. Ashcroft offers a smarter solution: pressure gauges with built-in overpressure protection. With over 170 years of innovation behind us, Ashcroft understands the harsh realities of industrial applications and we engineer products that perform in the most extreme conditions. Read this article to learn about two pressure gauges that are designed with XRA Overpressure Protection to handle pressure surges internally, eliminating the need for external components and improving system reliability.

In chemical and petrochemical systems, or any application that requires you to measure differential pressure (DP) with high static pressure and low differential pressure, reliability and corrosion resistance are crucial for safe instrumentation operation. If your pressure measuring instruments aren’t compatible with your process, you may face equipment damage and downtime. Ashcroft has been a leader in pressure instrumentation since 1852. During that time, we have answered questions from customers about differential pressure and the measurement solutions we offer. In this article, you will get a quick overview of differential pressure and learn about two of the several differential gauges we offer, including the Ashcroft® 5503 DP Gauge and Ashcroft® F5504 DP Gauge. By comparing the similarities and differences, you can determine which may be a better solution for your specific application. You will also see additional resources that you can explore to deepen your knowledge further about differential pressure and considerations for choosing pressure gauges.

Depending on the industry and application, your choice of pressure gauge construction can significantly affect the performance and lifespan of your instrument and your operation. Bourdon tube pressure gauges are known for their reliability and accuracy, making them a common choice for use across process, industrial and OEM markets. Ashcroft is a pioneer in pressure measurement instrumentation and holds the distinction of acquiring the U.S. patent rights for the Bourdon tube from its inventor, Eugène Bourdon, in 1852. This led to the widespread adoption of the "Ashcroft Gauge" in American industry, including railroads, steam locomotives, maritime vessels, factories and industrial plants. Over the years, Ashcroft has continued to innovate, developing various Bourdon tube constructions to meet the evolving needs of different applications. Read on to learn about Bourdon tube construction types, how they operate and where they work best. You will find links to additional articles and resources related to pressure gauges with guidance on selecting the most suitable one for your particular requirements.
