    KEY TAKEAWAYS

    - (RTD): These temperature sensors are particularly useful for temperature measurement over an extended period, and can often be more precise than thermistors and thermocouples for many applications.

    - Accuracy with this temperature sensor is also crucial, which means you need to consider which type is going to be the most accurate based on the temperatures you record most often.

    Choosing a suitable temperature sensor for your industry is not always straightforward. Due to environmental factors and even sensor calibration techniques, what works accurately for one industry may not work accurately for another. 

    When you’re trying to reduce measurement uncertainty and enjoy the most accurate temperature system for your line of work and environment, it’s worth comparing what options you have at your disposal. Some of the following information may help you with this process. 

    Thermocouples for High Temperatures

    Some of the most popular temperature sensors by Pyrosales are thermocouples, which are a desirable option for many reasons. Thermocouples are not only compact for various industries, but they’re also robust to handle daily use while also being fast to provide an accurate temperature quickly. 

    Thermocouples withstand high temperatures, which is often crucial for industries like engineering with the use of metals and chemicals and the creation of heating types. Many people also like thermocouples because you can place the sensing junction close to the most accurate point of measurement and can even embed them in equipment and materials. 

    Thermistors for Low Temperatures

    If you’re looking for a temperature sensor that doesn’t need to handle high temperatures but must be accurate, thermistors may suit your needs. They are sensitive, precise and responsive, and suit temperatures less than 300 degrees Celsius or 572 degrees Fahrenheit. 

    Thermistors can also be placed in protective metal to make them suitable for higher temperatures but at the cost of thermal responsiveness. They are often used in fire alarms, ovens, and refrigerators. 

    Resistance Temperature Detector (RTD) for Precision

    In industries or specific tasks that require absolute precision and stability, engineers and other professionals rely upon resistance temperature detectors, also known as RTDs.

    These measurement devices generally consist of fine wire featuring copper, nickel, or platinum around a glass or ceramic core and are used in laboratories and industrial processes. 

    What to Consider When Choosing a Temperature Sensor

    After learning about the different temperature sensor options on the market, it’s important to think about your own industry and how each type can be of value based on your needs. 

    One of the first considerations is durability, which counts for a lot in industries where measuring high and low temperatures is paramount.

    Ease of use, how straightforward the calibration process is, and the environment in which it’s going to be the most valuable are also worth considering. The more research you do into the different temperature sensors for sale, the more confidence you can have in your decision. 

    We have many different temperature sensors at our disposal, which is good news when you think about how complex and wide-ranging engineering and related fields are. However, there’s no denying that some are better suited for some jobs than others. Consider this information above so that you can have all the facts before you make your choice.
