Thermometer Design Problem There is a need to design a thermometer that can read from 250 C to 1000 C to monitor the temperature of a rocket’s nose cone. The output will feed a 0- to 5-V ADC prior to transmission of the temperature data to the ground. A reading of 250 C will deliver 0 V to the ADC, while 1000 C will deliver 5 V. Select from Figure P4–72 an appropriate thermocouple with sufficient voltage spread and design the instrumentation amplifier. Other criteria are: the transducers have a 15-V series resistance, the fewer OP AMPs the better, since power is limited, the maximum OP AMP gain is 1000, and the bias voltage, if needed, must be from the available 15-V supply.
