MultiSim Electronic Thermometer

Design an electronic thermometer in MultiSIM with the following specifications and constrains: 1. The thermometer will have two simultaneous outputs: Degrees Fahrenheit and Degrees Celsius. 2. A DMM will be connected to each output to produce a readout, with the output variable in volts. 3. Independently of the chosen variable, the decimal point in the readout must correspond to the decimal point in the temperature. For example a readout of 33.4 at the output for degrees F, should indicate 33.4 °F. Same approach for degrees C. 4. The electronic thermometer must have a range of -100 °F to +100 °F and -100 °C to +100 °C 5. The sensor will be the LM34 Temperature-to-Voltage transducer manufactured by National Semiconductor. 6. The Operational Amplifier that is available is the µA 741. 7. As many Op Amps as it needs can be used. 8. as many passive components as needed can be used, but only has access to 5% tolerance resistors. Using the table below, if calculations indicate a resistor of 2,345 Ω, a 2,200Ω or a 2,400Ω resistor will then be chosen. 5% Standard Values Decade multiples are available from 10 Ω through 22 MΩ 10 11 12 13 15 16 18 20 22 24 27 30 33 36 39 43 47 51 56 62 68 75 82 91 1. The only voltage sources available for this are fixed sources of -15V and + 15 V. 2. The conversion factors between temperature systems are as follows: °F = (°C x 1.8) + 32 °C = (°F – 32) / 1.8
