Ashcroft has written other articles on selecting the best pressure gauges or pressure transducers for ammonia applications (see links at the bottom of this piece). However, we noticed we were still getting questions from people about the ammonia element itself. So, for the industry novice, this article will take a step back to address those specific questions. Ashcroft pressure and temperature instruments are used in virtually every type of industrial application, including ammonia, so it is our job to know how they will perform in every situation. Here we will review a couple of ammonia applications, and what to look for when selecting the best pressure gauge for your specific needs. At the end of the article, you will find additional resources that may interest you.

If you work in any industry where you need pressure instrument assemblies mounted on diaphragm seals, fluctuations in ambient temperature can affect the accuracy of your pressure instrumentation, especially in low-pressure systems. To help minimize temperature fluctuations and improve the accuracy of your instrument readings, we recommend keeping the fill fluid volume as low as possible using a low-volume tee fitting in your diaphragm seal assembly. As an industry leader in pressure and temperature instrumentation since 1852, Ashcroft developed a series of Understanding the Basics articles that cover common process industry topics and terms. If you are new to manufacturing or process applications or just want a refresher, this is a great place to start. Read this article to learn the basics of low-volume t-fittings, including what they are, how they work and the benefits of using them as part of your assembly for these types of applications.

Industries involving liquids such as chemical/petrochemical, oil and gas, and water/wastewater, are constantly challenged by corrosion. Understanding the different types of corrosion and how they occur is the first step in protecting your process instruments from its damaging effects. As a leading authority in pressure and temperature instrumentation, Ashcroft® offers valuable insights into corrosion and its impact on businesses. This article explores the different types of corrosion, the factors influencing corrosive environments, and the significance of selecting compatible materials for process instrumentation. Additionally, discover key considerations for choosing pressure instrumentation capable of withstanding harsh corrosive conditions.

Consistently accurate temperature measurements are vital to several industrial processes in numerous industries from construction to energy to manufacturing. Although many instruments can measure the temperature of gas and liquid in these processes, thermocouples are among the most popular thanks to their simple design and versatility. Over time, however, the thermocouple’s performance may tail off for any number of reasons. Two of the most common are drift and elevated temperature. As a leading authority in temperature measurement instrumentation, we help customers understand the factors to consider when selecting instruments and the steps needed to keep systems running efficiently. If your process includes temperature measurement with a thermocouple, this article will explain why it is important to calibrate your instrument and how to do it. You will also get access to helpful resources that can help you gain deeper knowledge on the subject of temperature sensors.

If your job involves the risk of a fire or explosion due to an explosive element that is present, you work in a hazardous location. These environments require strict adherence to safety protocols and regulations to protect both personnel and equipment. Even a small incident in these environments could lead to costly downtime or worse. Ashcroft is a trusted brand of pressure and temperature instrumentation that can be found in countless hazardous locations across the globe. We have a tremendous amount of experience in developing products that are built to ensure smooth operations and the safety of your team. In this Understanding the Basics article, you will learn more about hazardous locations, the organizations and standards that govern them, code enforcing authorities, how to prevent explosions and more. Throughout the article, you will also find helpful links and additional resources where you can gain additional knowledge about products and best practices.

In another Ashcroft® Understanding the Basics article titled, What is a Pressure Gauge? you learn that manufacturers of pressure gauges must follow certain global standards to ensure all of these instruments function the same way. The standards that we are referring to are ASME B40.100 and EN 837-1. As a global leader in pressure instrumentation, Ashcroft is often asked which of these manufacturing standards we follow for our pressure gauges. The answer is both, and the reason is simple. This article will provide you with a brief overview of ASME B40.100 and EN 837-1 standards, what they cover, their similarities and their differences. Whether you are new to the world of pressure gauges, or you are looking for a quick refresher on the subject, you will gain a deeper understanding of these global standards after reading this piece. You will also find additional resources that may interest you when you are ready to go beyond the basics of pressure gauges.
