The resistance change is approximately -4.4% per C at 25 C. The large resistance change limits thermistors to narrow temperature ranges and low temperatures. However, in these situations, thermistors have greater accuracy and ambient temperature stability than RTDs or thermocouples. ead wire can be as long as 1,000 feet without significant error. Platinum RTD s electrical resistance values change approximately.85% per C. The DIN standard element is 100 ohms at 0 C, showing a nearly linear change of ohms between 0 and 100 C. Platinum RTDs provide very good system accuracy at very low temperatures to 1000 F. Two wire RTDs have significant errors when over 10 feet long. However, these errors can be eliminated by using 4 wire RTDs. Thermocouples are constructed with two wires of dissimilar metals that generate.05 MV per C at the hot junction. The cold junction must be maintained temperature constant by electronic means to avoid signal errors. ow signals and linear complexities make system accuracy and integrity difficult. However, thermocouples respond to temperature changes very quickly, are virtually impervious to vibration or other mechanical conditions, have a wide range and high temperature capability.
