B.

The time taken to attain 50% of the value of initial temperature difference

C.

The time taken to attain 63.2% of the value of initial temperature difference

D.

Determined by the time taken to reach 1000C from 0C

Answer ( Option C)

The time taken to attain 63.2% of the value of initial temperature difference

Solution

The time constant of a thermo couple is defined as the time required for the sensor to respond to 63.2% of its total output signal, when subjected to a step change in temperature.

Hence, the correct option is (C).
