In industries such as manufacturing, food processing, chemical production, HVAC and more, maintaining precise temperature measurement is important to ensure product quality and safety. Bimetal thermometers address challenging environments by providing accurate and reliable temperature readings that are necessary to protect your product, your process and your operators. But how do you determine the best bimetal thermometer for your specific application? As the product manager for temperature products at Ashcroft, a leader in pressure and temperature instrumentation, I can guide you through the selection process. Read this article to learn more about the functions and applications of bimetal thermometers and the key considerations to help you choose a high-quality option tailored to your requirements. I will also share some additional resources that can answer other questions you may have about these instruments.

Whether your industrial process involves challenging environments or everyday conditions, you will likely use a thermowell to prevent your temperature instrumentation from getting damaged. Without protection, it is easy for these sensors to become inoperable. One challenge field operators face with a thermowell is calculating the stem length to properly fit a thermometer or electronic temperature sensor. The Ashcroft technical team is often asked how this is done, so we created this article as a point of reference for you. Continue reading to learn about the different types of thermowells, factors to consider when selecting the right thermowell for your application, how they connect to the process piping and more. When you are done reading, you will also find additional resources that may interest you.

Gas-actuated thermometers and bimetal thermometers are both commonly used temperature measurement instruments in multiple industries due to their reliability and precision. However, they operate on different principles. No matter what industry you work in, if you require accurate temperature monitoring, understanding these thermometers can enhance both efficiency and safety in your operations. As the temperature product manager at Ashcroft – an industry leader in pressure and temperature instrumentation – I am often asked which of these instruments will be most appropriate for different applications. The answer, of course, depends on several factors. Read this article to compare the mechanics, applications, and advantages of gas-actuated and bimetal thermometers. Links to additional resources will also provide relevant information to help deepen your knowledge of temperature measurement. When you are finished reading, you will be in a better position to select the right instrument for your specific needs.

All industrial applications use some kind of temperature instrument to ensure process temperatures stay within an acceptable range. Choosing the right device can help protect your equipment and your operators from extreme temperature shifts. However, the type of instrument you use will depend on many factors, including the temperature limits of the operation and the instrument, the required output and more. As a global leader in temperature and pressure instrumentation, Ashcroft created this article as a high-level overview of industrial temperature measurement options. If you are an industry novice or just want a refresher on the basics, this can serve as a good reference piece. Read on to learn about the different types of industrial temperature instruments, how they work, where they are used and why you might choose one over another. When you are done reading, you will find additional resources related to temperature measurement that may interest you.

A thermowell is a device designed to protect temperature monitoring instruments from the damaging effects of corrosive media, high pressure and velocity in industrial applications. Without the protection of a thermowell, temperature instruments can become inoperable, putting your whole operation at risk. Ashcroft is a global leader in temperature measurement instrumentation. We created this article as part of our Understanding the Basics series to provide a foundation of information about thermowells. If you are an industry novice or just want a refresher on how thermowells work, this is a great place to start. In this article, you will discover where thermowells are used, learn about the different types of thermowells, see how they connect to the process piping and more. When you are done reading, you will also find additional resources that may interest you.

Thermowells are essential to protecting your thermometer or temperature sensor in your high-pressure or high-temperature applications. They can protect your investment and keep your measurements accurate, no matter how extreme the environment. One of the top questions we receive here at Ashcroft from those in the temperature measurement industry is how to properly fit a thermowell. What measurements are needed? What is a u-dimension and how does it factor in? Many factors are at play, and it can be easy to get the wrong size if you aren’t paying attention.
