There are so many factors to consider and endless combinations of products and configurations that will influence what you need for your specific application. So, how can you get the proper assemblies to suit your project’s needs? How do you start looking in the first place? These are questions that come up a lot in my discussions with customers. Luckily, my 20 years of industry experience, including the past five at Ashcroft, gives me the ability to share my expertise in this particular area. Read this article to learn the top five factors to consider when researching pressure instrument mounting assemblies, and how to choose the right assemblies that can protect your equipment and ensure successful processes for your specific application.

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.

If you work in oil and gas pipelines, chemical plants, refineries or anywhere that will require a thermowell to protect your temperature sensor from the process media, it is important to ensure that the device will work in the application. For instance, wake turbulence caused by your process has the potential to break the thermowell and damage your equipment. Calculating thermowell wake frequency can help. As a product leader at Ashcroft, with more than 40 years of industry experience, this is a topic that I talk to customers about often. In this article, you will learn what thermowell wake frequency is and how to calculate it. When you are done reading, you will understand the need to have a wake frequency calculation done and be more confident in your thermowell's ability to protect your temperature sensor. Plus, we will share additional resources that will deepen your knowledge of thermowells even further.

If you work in oil and gas, chemical and petrochemical, or any other industry that involves high heat, your challenge is to find instruments that are designed to withstand the extreme temperature conditions of the environment and your process media. For example, pressure gauges have specific temperature ranges. If your application goes beyond the instrument's limits, you may need to add an accessory to maintain the integrity and accuracy of your gauge. As the accessories product leader at Ashcroft, part of my job involves educating customers and distributors about the options available to keep their systems running safely and efficiently. In this article, you will learn how to protect your pressure gauges from getting damaged in harsh applications. You will also see links to additional articles and resources that will help deepen your knowledge of pressure gauges and the accessories that support them.

Pressure switches that are used for industrial applications involving any kind of liquid, such as water, oil or chemicals - or processes that have a risk of explosion - must meet specific standards. Choosing the wrong type of instrument for these challenging conditions can be dangerous for your operation and your people. As a territory manager for Ashcroft, customers often ask me to explain the difference between a NEMA 4/4X pressure switch and a NEMA 7/9. The short answer is that one classification is watertight (NEMA 4/4x) and one is explosion-proof (NEMA 7/9). But that response doesn't tell you what you need to know about these instruments before selecting the best switch for your specific needs. Read this article to learn the differences between these types of switches and how each is designed for a specific purpose. When you're done reading, you will have a clear understanding of the pressure switches, features and ratings to look for when choosing the best instrument for your application.

For instance, the pressure of a home water system does not necessarily need to be as precise as a medical sterilizer. However, over time, even the highest quality pressure instruments can become less accurate due to factors such as wear and tear, environmental conditions, and mechanical stress. This gradual decline in accuracy poses can lead to inefficiencies, safety risks, and compromised operations, making it critical to periodically calibrate your instruments to ensure they provide accurate readings. During my 13 years as a precision product leader at Ashcroft, I am often asked how calibration is done. Read this article to learn what is involved in pressure gauge calibration and the instruments you can use to ensure it is done correctly. At the end of the article, you will also see links to additional resources to help deepen your knowledge on this subject and more.
