Thermometer Design Problem
There is a need to design a thermometer that can read from $30°\text{C}$ to $300°\text{C}$ to monitor the temperature of an Unmanned Aerial Vehicle's (UAV) power supply. The output will feed a 0-V to 5-V ADC prior to transmission of the temperature data to the ground. A reading of $30°\text{C}$ will deliver 0 V to the ADC, while $300°\text{C}$ will deliver 5 V. Select an appropriate thermocouple with sufficient voltage spread from Figure P4-82 and design the instrumentation amplifier. Other criteria are as follows: the transducers have a $15-\Omega$ 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.
