Resistance Temperature Detectors (RTDs) rely on the predictable and repeatable phenomena of the electrical resistance of metals changing with temperature. The most common metals used for temperature sensing are platinum, nickel and copper.
In some cases, not using a thermowell can cause irreversible damage to your temperature sensor. In this article we will explain what is a thermowell, why you would need one, and what process you should follow when selecting a well for your project. Thermowells are tubular fittings used to protect temperature sensors in industrial processes…. Read more »
