RTD-TC-Compare
Comparison of Thermistors, Thermocouples and RTD's ... Unlike RTD's and thermistors thermocouples have plus and minus legs so polarity must be observed.
Comparision of Thermistors, Thermocouples and RTD's
Thermocouple - No resistance lead wire problems, Fastest response; RTD - Most stable, accurate, Contamination resistant,; Thermistor - High output, fast, Point temperature sensing.
Watlow - Temperature Sensor Comparison Guide
Since thermocouples measure wide temperature ranges and are relatively rugged, they are very often used industrial and process applications where accuracy may be a less important factor.
