Commonly manufactured using a platinum resistance element. More accurate and more linear than most thermocouples and generally much more costly and slower responding. Thermocouple - A temperature sensor based on the principle that a voltage is produced when two dissimilar metals. The junction produces a voltage in proportion to the difference in temperature between the measuring junction and the reference junction. Thermowell - A threaded or flanged closed end tube which is mounted directly to the process or vessel, designed to protect the thermocouple from the process surroundings.
Thermocouple wiring is color coded by thermocouple types.
Different countries utilize different color coding. Jacket coloring is sometimes a colored stripe instead of a solid color as shown. Go To ISE Thermocouple Data Sheet Page . For a complete listing click Products or Contents . Inc. All rights reserved.
