(c) A displacement sensor has an input range of 0 to 8 mm, which has been calibrated and the results are shown in Table 1.1 (assume that, apart from non-linearity error, all other errors are negligible). Displacement 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 (mm) --- Output voltage 0.0 8.2 15.7 24.5 33.1 39.3 48.2 55.1 64.0 (V) Table 1.1 (i) Calculate the sensitivity of the sensor. (ii) Estimate the non-linearity of the sensor. (iii) Outline the key issues to be considered if the sensor is calibrated at a local BCS (British Calibration Services) Centre. [8 marks]
