In many industries, temperature must be closely monitored to ensure smooth, safe operations. When measuring this or any other factor, accuracy is of utmost importance, so choosing the right temperature sensor demands proper consideration. Based on the measurements you record the most, varying temperature sensors will work best in different settings. Most likely, you will require a thermistor, a thermocouple, or a resistance temperature detector (RTD), so this blog will walk you through the best applications for each.
The main factors that affect which temperature sensor works best for you include your working environment and the duration of use. For measuring temperatures over an extended period of time, the best option is most likely an RTD. These temperature sensors are ideal for producing stable, accurate readings over long durations of exposure to operating temperatures. They are designed to be resistant to influence from their surrounding environment, generally consisting of fine wire equipped with copper, nickel, or platinum around a glass or ceramic core and are used in laboratories and industrial processes. At the same time, these sensors are complex and may not be necessary for your specific application.
In settings where your temperature sensor will not be exposed to high temperatures, a thermistor works the best for accurate readings of low temperatures. In fact, thermistors produce sensitive, precise, and responsive results for environments where the temperature is less than 300 degrees Celsius, making them popular in fire alarms, refrigerators, and ovens. They may also be placed within a protective metal to make them suitable for higher temperatures, but this will compromise their thermal responsiveness.
Lastly, thermocouples are popular for many reasons across many industries. Not only are they compact, but they are also robust enough to handle daily use while being fast enough to provide an accurate temperature quickly. As they can withstand high temperatures better than thermistors, these are used frequently in industries like engineering sectors, where the use of metals, chemicals, and the creation of heating types is common. Additionally, their sensing capabilities are easy to calibrate for accuray.
All things considered, a few factors go into determining the best temperature sensor for your specific application. Depending on your industry, it is important to consider durability, so you do not choose a temperature sensor that malfunctions in your specific temperature range. It is also helpful to find a sensor with a straightforward calibration process so you are comfortable operating your device. The more research you do, the better equipped you will be to work with your specific sensor.
