Question 49
INNAT2 marksNeeds review
The hot junction of a bare thermocouple, initially at room temperature (30°C), is suddenly dipped in molten metal at
s. The cold junction is kept at room temperature. The thermocouple can be modeled as a first-order instrument with a time constant of 1.0 s and a static sensitivity of 10 μV/°C. If the voltage, measured across the thermocouple indicates 10.0 mV at
s, then the temperature of the molten metal in °C is ________.Log in to check the answer
