A thermocouple circuit produces an amplified voltage difference of 0.5V when there is a change in temperature of 10°C.Thermocouple amplified voltage at 30°C is 2.5V.The thermocouple circuit is to be used as a temperature sensor to maintain an oven temperature between 40°C and 80°C by switching ON and OFF the power supply to the oven.The oven is to be controlled by schmitt trigger in connection with the thermocouple circuit.The schmitt trigger is to be connected to ±15V.
(a) Determine schmitt trigger voltage levels (upper and lower trigger level)
(b)Sketch hysteresis loop and show all necessary voltage levels
(c)draw the schmitttrigger circuit and determine reference voltage
