In harsh process environments, even the most durable components can degrade over time—especially thermowells, which are your first line of defense for temperature sensors. Exposure to corrosive chemicals, high-velocity flow or abrasive media can wear down thermowells, risking measurement accuracy and system reliability. That’s where coated thermowells come in. As a trusted leader in temperature instrumentation, Ashcroft helps engineers extend equipment life and ensure process stability by offering different coatings for specific conditions. In this article, you’ll learn how thermowell coatings work, the different types available and how to choose the best option to protect both your instruments and your process.

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.

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.

If you work in process industries like oil and gas or chemical/petrochemical, you know that a thermowell is a critical component that can help ensure the safe operation of your systems. That's because it is the thermowell's job to protect the temperature monitoring instruments from system pressure, high-velocity flow and corrosive media. However, keep in mind that selecting the wrong thermowell to do the job can have negative consequences that will put the safety of your process and your people at serious risk. Ashcroft has been in the temperature measurement business for decades. As the firm's temperature product manager, I know that flanged thermowells are typically the preferred choice for these applications because of their design and cost. In reality, though, even when the cost feels prohibitive, there are certain situations where a Vortex Thermowell may be your only option. In this article, you will learn about the forces that can make a thermowell fail and the factors to consider when determining whether the Vortex Thermowell is worth the added expense. You will also get links to additional resources related to this topic that may be of interest to you.
