What is a Resistance temperature detector and what are its types?

What is a Resistance temperature detector? The resistance temperature detector is basically a resistance thermometer, and it is used to measure the temperature. RTDs are replacing thermocouples due to their better accuracy and repeatability. The RTD works on the principle that the resistance of the RTD element would vary with the change in temperature. RTDs …

Different types of Temperature Sensors used in industries

Introduction Electronic temperature sensors come in two basic varieties: resistance devices and voltage devices. A resistance device is one in which the resistance varies with temperature. Resistance devices can be further classified as a PTC (Positive Temperature Coefficient) device, or an NTC (Negative Temperature Coefficient) device. The resistance of a PTC increases with an increase …
