For platinum thermocouples, lead wires are made of___________________?
Correct answer: A. Copper & copper-nickel alloys
- A. Copper & copper-nickel alloys
- B. Copper & iron
- C. Iron & nickel
- D. Tin & nickel
Explanation
Platinum thermocouples use copper and copper-nickel alloy compensation or lead wires because these combinations reproduce the thermoelectric behaviour over the connecting section. Ordinary copper and iron leads would introduce a different thermocouple junction effect.
