If you experiencing issues with diaphragm seal failure in your process, you are not alone. In harsh applications that involve corrosive media and other challenging conditions, diaphragm seals are your primary line of defense in protecting your pressure instruments from becoming damaged. At Ashcroft, we've seen practically every scenario that can cause a diaphragm seal to fail, leading to inaccurate readings and costly downtime. In this article, we will review how a diaphragm seal works, explore the three conditions that account for the majority of diaphragm seal failure — corrosion, high temperature, and fluid fill leakage — and offer some corrective measures to fix these issues. When you are done, you will have a better understanding of why diaphragm seals can fail and be able to identify and prevent potential issues in your own process. You will also find links to additional resources that will help address other diaphragm-related questions you may have.

Natural Gas | pressure gauge | R110

If you are among the growing number of natural gas vehicle (NGV) manufacturers that use Compressed Natural Gas (CNG) or Liquified Natural Gas (LNG) power-generating components, you know that safety in your process is paramount. That is why it is important to ensure any pressure measurement instrumentation used in these applications has proper approvals from applicable governing agencies. However, acceptable approvals for cars and trucks in the U.S. are different from approvals you will need for vehicles made for the overseas market. For instance, all NGV vehicles in Europe must follow Regulation No. 110 (R110) safety regulations. As a recognized leader in pressure and temperature measurement instrumentation for industrial and OEM markets, Ashcroft receives daily questions about the challenges our customers are facing. In this article, you will learn more about CNG and LNG-powered vehicles and why R110 approvals are necessary for any instruments used in the production of NGV vehicles that are sold in Europe. When you are finished reading, you will also receive additional resources to help you select the best pressure instrumentation to meet your specific needs.

Isolation Rings | water & wastewater | isolators

Isolation rings are also known as isolators. They are designed to protect pressure-measurement instruments from the damaging effects of corrosive media in water/wastewater treatment plants, chemical processes, and mining facilities. To fully appreciate the importance of using these instruments in your operation, we need to start with a basic understanding of how they work. Ashcroft has been in the pressure and temperature instrumentation business since 1852, and we wrote this article for the industry novice. We hope you can use it as a foundation for understanding the important role isolation rings play in challenging applications. Read on to learn how isolation rings protect pressure-sensing instruments in your applications, the three most common types of rings, how they are constructed and the primary benefits of using these instruments. When you are done reading, you will also find additional, related resources in case you want to go beyond the basics of this topic.

water & wastewater | diaphragm seals

By: Darren Lewandowski
April 8th, 2024

Oil & gas, water/wastewater, chemical and petrochemical industries rely on accurate and repeatable pressure measurement instruments to ensure processes run safely and efficiently. However, without proper protection, the internal (wetted) components of those pressure gauges, transmitters, transducers and switches will become damaged from the corrosive materials found in these harsh applications. Diaphragm seals are the ideal solution for protecting your pressure sensors from potential damage because they can isolate the sensing components from the process media. But choosing the right diaphragm seal for the job requires you to consider which wetted materials are best suited for your specific application. Ashcroft can help. We have been an industry leader in pressure and temperature instrumentation for decades and often help our customers address this very challenge. In this article, you will learn the four factors to consider when choosing your diaphragm seal material. When you are done reading, you will have the information you need to be more confident in your purchasing decision. You will also see additional related resources to address other diaphragm seal questions you may have .

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.
