Thermocouple General Information

Thermocouples -200 ° to 2320 ° C is widely used in various processes. Thermocouples two different metal alloys, obtained by welding the ends of the temperature measurement element. The point boiled HOT SPOT , the remaining two open ends COLD SPOT is called. With thermocouple cold junction temperature difference between the hot spot is formed. Proportional to the temperature difference voltage in mV at the ends of the cold spot is produced. With hot spot no matter how cold spot temperature distribution of the generated voltage is proportional to the temperature difference between the hot and cold spots
