RTD Introduction ▶ Check out the full blog post over at https://realpars.com/temperature-sensor RTD or “Resistance Temperature Detector” is a device the resistance of which varies with the temperature. Since it is a “passive” device, an external electrical current should be applied to it and then the voltage drop across it can be measured. This voltage is a good indication of the temperature. Watch the video and answer the question. Why is RTD excitation current kept extremely low? #Temperature
