This article was originally published on February 9, 2022, and was updated on April 3, 2024. Pressure gauges are often used in challenging environments where they could be exposed to extreme temperatures that may damage them or impact their accuracy. These extreme temperatures can come from a variety of sources such as the surrounding environment (ambient temperature), or the temperature of the process media being measured (media temperature). How do you minimize the effects of temperature on your instrumentation and protect your pressure gauges from damage? Read on to learn the effects that temperature can have on pressure gauges and their performance. Plus, you will gain insights into how you can address these issues to keep your gauge working at peak performance.

This article was originally published on January 10, 2022, and was updated on March 13, 2024. If you work in the oil and gas or chemical industry, or even in a power plant, you know that a manifold valve blocks the flow of fluid in your system so the process media will be isolated from pressure instrumentation. You also know that a block-and-bleed manifold blocks the upstream process media from the instrumentation while allowing the bleeding off (venting) of the remaining fluid from the system on the downstream side of the manifold. But when you need to know which manifold valve is the right one for your specific process, that's where we can help. Ashcroft is a leading authority in pressure instruments and the accessories that help them operate at peak performance. As the senior product manager for this segment of our line, I have had the opportunity to train many customers and distributors on this very subject. Read this article to learn the various manifold valves, how they are different and the mounting options you can choose from. When you are done, you will also find additional resources that may be of interest to you.

Pressure gauges are used in various environments where they can be exposed to extreme temperatures. These temperature sources can be either from the ambient surrounding environment temperatures, or the actual temperature of the process media. You need instrumentation that can withstand extreme temperature ranges. Do you have the best instruments and accessories for your application?

pressure gauge | measurement instrument accessories | diaphragm seals | instrument assembly

This article was originally published on April 18, 2022, and was updated on April 17, 2024. No matter what industry you work in, diaphragm seals (also referred to as isolators) and welded assemblies are used to protect your pressure and temperature instrumentation from corrosive process media. After decades of making quality pressure and temperature gauges and sensors to help keep processes performing reliably and efficiently, Ashcroft has seen just about every scenario where something can go wrong. One reason we like to share our expertise is to help people like you who may be experiencing a similar issue that we can help solve. In this article, you will learn what a welded diaphragm seal assembly is and how it is used to help mitigate the damaging effects of high temperature, pulsation and vibration endured by your instruments. You will also see how these assemblies can ensure reliable and accurate pressure readings of your process. When you are done, you will find links to additional resources that can help you learn more about related topics.

water & wastewater | measurement instrument accessories | diaphragm seals

This article was originally published on January 31, 2022 by John Varkonda and was updated on May 8, 2024, by Todd Thomas. 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.

pressure transducers | measurement instrument accessories

Pressure transducers can be used in many challenging environments where they may be exposed to extreme temperatures but are expected to operate reliably and predictably. These challenging temperature exposures can come from a few sources such as the surrounding environment (ambient temperature), radiation (sunlight), or the temperature of the process media being measured (media temperature).
