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.
If you read my article, “Why and When is RTD Calibration Necessary?” you learned how Resistance Temperature Detectors (RTDs) such as our S81 and S50 are a better choice than thermocouples for temperature process measurement because of their repeatable, high-accuracy measurement capabilities. More specifically, RTDs are ideal for demanding applications like chemical and refining processes that depend on precise temperature measurements. But to really understand RTD calibration, you also need to know how an RTD works. When I joined Ashcroft — a leader of temperature and pressure instrument solutions across the globe— I brought more than 20 years of temperature application experience with me, and I am happy to share my knowledge with you. In the following article, you learn more about how RTDs work, the different levels of accuracy in RTD calibration and the national and international standards that they are measured against. You will also be directed to additional resources and contact information in case you are ready to take the next step in your decision to select the best temperature measurement solution for your specific application.

If you are an industrial instrument designer, you have several temperature measurement options available to you. These include Infrared, Bi-Metal, Gas-actuated thermometers, Thermistors, Thermocouples and RTDs. Industrial automation and process applications predominantly use thermocouples and Resistance Temperature Detectors (RTDs) instrumentation such as our S81 and S50 because of their proven ability to provide accurate and reliable readings. Each of these sensors has unique advantages and can be configured to match the application needs for optimum service life and performance. Based on my experience working with instrumentation and reliability teams, I’ve seen and compared the benefits of both options. Thermocouples, for example, are often chosen for a robust signal, cost-effective price and ability to withstand most process plant specifications, including harsh vibration and high-temperature range up to 2300° C. RTDs, on the other hand, are the top choice for applications demanding higher accuracy levels and minimal drift. In this article, you will learn more about the benefits of RTDs and why RTD calibration is important to maintain highly accurate and repeatable readings for a longer life span.
There are many instruments used for temperature measurement, but electrical temperature sensors tend to be the most common method. A resistance temperature detector or RTD temperature sensor converts the measured temperature value into an electrical signal. But do you know how an RTD actually works? This article will discuss RTD sensors, their function and how they can help provide accurate temperature measurements for your application.
Temperature sensors are key components in helping to ensure a safe and reliable application. RTDs and thermocouples both provide accurate and repeatable temperature measurements for your process. But, how do you know which sensor is the best one to use in your application?
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?
