According to the Environmental Protection Agency (EPA), groundwater serves as a crucial resource for half of the U.S. population. Reliance on this vital natural resource is especially significant in regions with scarce rainfall, limited surface water availability, or high agricultural demands and population. As a leading manufacturer of pressure and temperature instrumentation, Ashcroft understands the challenges of protecting this vital resource. In this article, you will learn about submersible pressure transmitters and how they are used to monitor water levels and provide essential information to water management personnel. You will also see examples of four common applications where submersibles are used and some challenges these instruments may encounter while in use. When you are done reading, you will find additional, related resources that may be of interest when you are ready to go beyond the basics of this topic.

Maintenance, reliability, process and Health Safety Environment (HSE) teams rely on accurate and stable temperature measurements to meet their goals. Thermocouples, new out of the box, are a critical tool for these measurements that help plant personnel maintain safe and efficient operations. Today, instrument designers use a wide array of thermocouple types, such as Type K, Type E and Type T to measure temperatures in applications ranging from cryogenic temperatures of -196 °C to the extremes of 1700 °C. This article will discuss how thermocouple calibration offers added benefits that promote process improvements and support compliance requirements. When you are done reading, you will also find additional related resources that can help you gain more insight into these important instruments.

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.

Not every application is the same, so you need to get the right equipment for your specific needs. When it comes to temperature measurement, inaccurate readings can severely impact your process. So, how can you ensure you are correctly and reliably monitoring temperature? Whether your application is for light-industrial temperature measurements or critical heavy-duty installations, Ashcroft®, an industry leader in pressure and temperature instrumentation, has developed a line of reliable thermocouple probes that are custom-configured to meet your specific application requirements. This article will discuss how to choose the best thermocouple lead wire for common applications. When you are done reading, you will also find additional related resources that can help you gain more insight into thermocouples.

In a recent Understanding the Basics blog article, we reviewed how temperature is measured in industrial applications using different types of thermometers. In this article, we will focus on the temperature sensors used to measure temperature in original equipment manufacturing (OEM) systems, light industrial processes or even more complex applications. No matter what the purpose, inaccurate temperature measurements can have serious consequences for your entire operation, so you'll want to be sure you use accurate and reliable instruments to do the job. If you are new to OEM applications or simply need a refresher on the basics of temperature sensors, you've come to the right place. Here we will review different types of temperature sensors, how they work, and what to look for when selecting the best option for your specific needs. At the end of the article, you will find additional resources related to temperature measurement that may interest you.

If you are new to the world of diaphragm seals or just want a refresher on how they work, you've come to the right place. A diaphragm seal (also known as an instrument isolator) is a protective mechanism that connects to the process side of a pressure measurement instrument. The primary function of a diaphragm seal is to prevent the sensing element of your pressure instrument from getting damaged by any corrosive process media or clogging in your application. Without using a diaphragm seal in place to protect your instrument, you will not be able to accurately and effectively measure the pressure in your system, putting your entire operation at risk. Why trust Ashcroft? We are an industry leader in pressure and temperature measurement instrumentation and are often asked for insight regarding the benefits of these instruments and how they work. In this article, I will review how diaphragm seals are used in different applications and provide links to additional resources in case you want to expand your knowledge on the subject further.
