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.

If your business currently depends on fossil fuel, you may be thinking about transitioning to a cleaner energy solution like hydrogen because it has less impact on the environment. While hydrogen may be a great solution for electric trucks, cars, buses and materials handling equipment, it is important to understand the unique standards and safety requirements for the production and transportation of this highly combustible substance. Temperature sensors used in hydrogen applications must adhere to rigid standards to maintain a safe working environment. For decades, Ashcroft has been offering a wide range of temperature sensors to clients in a variety of fields, including hydrogen fuel production. Using the knowledge we have gained, we are able to guide customers to the best solution for their needs. In this article, we’ll touch on the advantages of hydrogen energy, its risks and challenges, and some real-world examples of how sensors are used in hydrogen environments.

Temperature can be measured with a variety of methods. Glass thermometers, resistance temperature devices (RTDs), bimetal instruments, gas expansion (gas-actuated) thermometers and infrared radiation, to name a few. Each offers a unique set of advantages for specific applications. Another extremely common temperature measurement device is the thermocouple. Its simple design makes it remarkably versatile, reliable and cost-effective. But how does a thermocouple work? This article will describe the function of thermocouples, the different types and their material composition.

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?
