Resistance\ntemperature detectors (RTDs) are temperature sensors that contain a resistor\nthat changes resistance value as its temperature changes, basically a kind of\nthermistor. In this resistance sensor, the resistor is actually a small strip\nof Platinum with a resistance of 100 ohms at 0°C, thus the name PT100. You can\nalso use this sensor to measure any kind of variable resistor that has about\n100 ohm of resistance (but can range from half to double that) Compared to\nmost NTC\/PTC thermistors, the PT type of RTD is much most stable and precise\n(but also more expensive) PT100's have been used for many years to measure\ntemperature in laboratory and industrial processes, and have developed a\nreputation for accuracy (better than thermocouples), repeatability, and\nstability. However, to get that precision and accuracy out of your PT100 RTD\nyou must use an amplifier that is designed to read the low resistance. Better\nyet, have an amplifier that can automatically adjust and compensate for the\nresistance of the connecting wires.
