The time constant of a thermocouple is

Question

RRB Paper · Accepted Answer

The Time Constant of a thermocouple 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.

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 100°C from 0°C

The correct answer is `No. 3: The time taken to attain 63.2% of the value of initial temperature difference`
