For instance, in environments with high oxygen levels, you need to ensure your pressure instruments are free of contaminants to prevent a fire. Even though oxygen itself is not flammable, it can cause other materials like dust, oils and lingering residue to easily ignite and burn with intensity. Cleaning for oxygen service is an effective safety precaution you can take to prevent this from happening in your application. As a product sales leader at Ashcroft, a leading authority in pressure and temperature instrumentation, I am often asked if we offer this service to our customers. The answer is yes, depending on the application. However, before you decide if it's right for you, take a few minutes to see what the service involves. Read this article to learn more about the benefits of cleaning for oxygen service and the process we use to be sure your instruments are safe to use in high-purity gas or pure oxygen systems. You will also see additional articles and resources that are relevant to pressure gauge selection and care.

Managing hydraulic systems in mobile construction equipment, fuel pumps, industrial machinery and automotive braking systems for example - is no easy task. Because these systems use liquids in various forms to generate power, the inherent pressure levels of hydraulics have to be properly managed. Otherwise, the consequences can include reduced performance, potential equipment damage, or even physical injury to system operators. That's where hydraulic pressure gauges can help. These instruments play a critical role in regulating pressure by monitoring levels in either a specified part or the entire system to ensure things are operating normally. The challenge is choosing the pressure gauge that will work best in your hydraulic application. As a pressure gauge product lead at Ashcroft - a recognized authority in temperature and pressure solutions - I have seen many scenarios where the wrong pressure gauges were selected and the impact that decision had on operations. Read this article to learn about the five pressure gauge features I consider most important for hydraulic applications so you can be confident about selecting the best option to meet your specific needs. Let’s get started.

It includes a wide range of temperature-measuring instruments in various shapes and sizes for a multitude of uses. Whether it's a thermometer used to monitor temperature in a chemical plant or one to check your child's fever, the quality and cost can differ significantly. As a temperature product manager at Ashcroft, a leader in industrial pressure and temperature instrumentation, I have more than 25 years of experience in this field. In that time, I have gained a deep understanding of the pricing and cost factors in the industrial temperature market. While there are too many types of thermometers to cover, read this article to learn what makes bimetal thermometers different from traditional temperature measurement instruments and the factors that influence their pricing.

Generally speaking, a siphon is a small, heat dissipation device used to protect pressure instruments from high-temperature media and reduce the possible damaging effects of rapid temperature change. There are different types of siphons, each designed for specific applications, from industrial to everyday use. This article will focus on industrial applications found in power generation, oil and gas, chemical and petrochemical plants and water/wastewater management, to name a few. As part of Ashcroft's Understanding the Basics series, this article will explore the different types of siphons used as heat dissipators in both steam and non-steam applications. Continue reading to learn which siphons are used for these purposes and how they work. You will also see links to additional information on these instruments and resources to enhance your understanding of maintaining instrument safety in challenging environments.

Accurate low-pressure monitoring is crucial for safety in air flow measurement, leak detection systems cleanrooms, isolation rooms and other critical applications in healthcare, semiconductor manufacturing and more. However, measuring very low pressures in small volumes with accuracy and repeatability requires a specialized sensor. It is the sensor’s design, manufacturing process and installation method that will determine whether or not it can deliver the long-term stability, accuracy and resolution necessary to provide meaningful measurements. That's where microelectromechanical systems (MEMS) can help. Ashcroft, a recognized leader in pressure and temperature instrumentation, and its parent company Nagano Keiki Co. LTD have a proven track record of manufacturing excellence in low-pressure pressure sensors with MEMS technology. Read this article to learn more about MEMS, how it works in low-pressure applications and the pressure sensors available to keep low-pressure environments working with precision and reliability.

If you are just starting a career in oil and gas, chemical processing or any industry that involves flammable materials, dust and other potentially ignitable substances, you need to understand the dangers associated with hazardous locations. This includes knowing what to look for when purchasing instruments for challenging and potentially explosive applications. As a product technical leader at Ashcroft - a recognized authority in pressure and temperature measurement instrumentation - I understand these challenges well. In this article, you will find valuable insights to help you navigate the complexities of monitoring temperature in hazardous location applications. This includes a definition of a hazardous location, the agency standards and approvals required for equipment used in these areas and why temperature instruments, in particular, to be fully certified to ensure the safety and compliance of your operation. When you are done reading, you will have a foundation of information and be more confident about your instrument choices for these challenging applications. You will also have access to additional resources that will deepen your knowledge of RTDs and thermocouples.
