QUESTION 2 In Mars rover project, NASA has used a displacement transducer to measure the distance travelled by the Mars rover during it mission to Mars. The displacement traducer collects the data and convert it into voltage and then encrypted data is transmitted to earth. The specification of displacement transducer used in the project is given below in Table 1. A built-in voltmeter is used in the Mars rover indicate the displacement transducer output in volts and transferred back it to the earth station. The voltmeter having a specified accuracy of :0.1% reading with a resolution of R. The measured temperature variation at Mars 1100°C, estimate an uncertainty in a nominal displacement of D at the design stage. Assume 95% confidence. Also calculate sensitivity of the measurement system Resolution = R = highlighted digit of your students Deg (20154435) mv R= Measure displacement D = Highlighted digits of your students De.g (20163541) cm In case if your highlighted digit is zero select the next non zero number. Parameter Magnitude Linearity error 0.25% of measured reading Drift 0.05% / °C of measured reading Sensitivity error -0.25% of measured reading Output 0-9 V dc Range 0-9 cm
