Refer to the drawing of a simple thermocouple circuit (see figure below).
The measuring and reference junctions are located inside the reactor containment building while the instrument is located in a remote location outside the containment building.
Thermocouple temperature indication is initially 500°F.
An ambient temperature decrease outside the containment building lowers the temperature of the instrument by 10°F, while the measuring and reference junction temperatures remain constant.
Thermocouple temperature indication at the lower ambient temperature will be…
A. 490°F.
B. 500°F.
C. 510°F.
D. none of the answers.
