Rtds vs thermocouples

WebApr 19, 2007 · RTDs (resistance temperature detector) use the fact that some metals (usually platinum) increase their electrical resistance as they get hotter. To measure the change, the sensor output is fed into a Wheatstone bridge with a reference voltage. RTDs have characteristics that compare well against thermocouples: More stable; More accurate; WebWhile they often have lower accuracy and stability than RTDs, thermocouples do typically feature a wider temperature range. Thermocouples can read temperatures as low as -450 …
