The time constant of a thermocouple is
The time taken to attain the final temperature to be measured
The time taken to attain 50% of the
value of initial temperature difference
The time taken to attain 63.2% of the
value of initial temperature difference
Determined by the time taken to reach 1000C from 0C
The time taken to attain 63.2% of the
value of initial temperature difference
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).
