A type K thermocouple is connected to a differential amplifier with an amplification gain of 100 and is used to measure the liquid temperature in a tank. For a certain measurement, the amplifier produces an output voltage of 3.5 V at the thermocouple reference junction of 23.5 °C. Calculate the measured liquid temperature based on the output produced. The thermocouple property of type K thermocouple is shown in Table Q2 (thermocouple voltage is in mV). Based on the calculated temperature, what is the new output voltage of the amplifier if the reference junction is suddenly changed to 27°C?

output produced. The thermocouple property of type K thermocouple is shown in Table
Q2 (thermocouple voltage is in mV). Based on the calculated temperature, what is the
new output voltage of the amplifier if the reference junction is suddenly changed to
27°C?
