Q6. a. A certain type of temperature transducer, designed to measure temperatures in the range 0-100C°,
consists of a thermistor. The thermistor has a nominal resistance of 1400 and forms one arm of a DC
bridge circuit, with the other three arms each having a resistance of 14022. The bridge output is measured
by an instrument whose input impedance can be assumed infinite. If, in order to limit heating effects, the
maximum permissible gauge current is 40 mA, calculate the maximum permissible bridge excitation
voltage. If the sensitivity of the thermistor is 340m2/C° and the maximum bridge excitation voltage is
used, calculate the bridge output voltage when measuring a pressure of 50 degree Celsius.
Figure QI shows the circuit diagram of a "Logarithmic Amplifier". In this
circuit the feedback resistor of a normal inverting amplifier is replaced by a
silicon diode. Since the current flowing through the diode increases
exponentially with the voltage across the diode, the voltage across the diode
will be proportional to the logarithm current flowing through it. Hence the
output of the circuit is proportional to the logarithm of the input voltage.
