5.9 A pressure transducer consists of a Bourdon tube elastic element connected to a potentio- meter displacement sensor. The input range of the Bourdon tube is 0 to 10 Pa and the output range is 0 to 1 cm. The potentiometer has a length of 1 cm, a resistance of 10 k2 and a supply voltage of 10 V. If the input pressure is 5 x 10' Pa, calculate: (a) the displacement of the potentiometer wiper (assume a linear Bourdon tube) the open circuit transducer output voltage (b) (c) the voltage indicated by a voltmeter of resistance 10 k2 connected across the potentiometer.
