Starting from the basic operational principles consider the following: In a clean-room product sensitive operation, a K-type thermocouple is used to measure the temperature of the external surface of an oven. The second junction is kept at the ambient temperature of 22C. The temperature of oven must be maintained between the minimum of 210C and the maximum of 250C. Calculate the voltages across the output terminal of the thermocouple for the minimum and maximum temperatures for the Seebeck Coefficient 41V/K and Thomson Coefficient is V/K2. What is the gain of the amplifier to raise the maximum generated voltage to 1V? [2 MARKS] What is the gain of the amplifier to raise the maximum generated voltage to 5V? When the oven door opens to change the contents, the ambient temperature of the room increases 27C and the temperature of the oven surface falls. If the temperature falls just below 200C warning alarm is set, calculate the voltage generated at the terminals to trigger the alarm? What is the alarm voltage?
