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.

In water and wastewater applications, corrosive substances or blockages from sludge or slurries can compromise your pressure and temperature instruments. How can you safeguard these instruments and maintain operational efficiency? A diaphragm seal offers protection, but not just any seal will suffice. You'll want a diaphragm seal with a flushing connection that can simplify the seal's cleaning process and prevent clogging. I've been working with Ashcroft - a leader in pressure and temperature instrumentation - for the better part of 33 years. Initially, I was the branch manager at an Ashcroft distributor, and for the past 10 years, I have been the Northwest territory manager. In both roles, I have helped customers understand the features and benefits of water and wastewater instrumentation. Read this article to learn what a flushing connection is, how it can help a diaphragm seal be more effective in harsh applications and when it's most advantageous to put one to work for you.
