Question 4 a) b) d) Identify and briefly describe TWO suitable sensors which could be used to measure temperature and TWO sensors which would be suitable to measure pressure. A linear temperature sensor produces an output voltage of 0-0.5 V when the temperature varies in the range 0-100°C. Calculate its sensitivity. Design a suitable amplifier circuit, based on an idealised operational amplifier which will produce an output voltage in the range 0-5 V for the sensor from Part b). Your answer should include identification of the amplifier type chosen, circuit diagram, component selection and calculations. A 12-bit analogue to digital converter (ADC) is to connected to the output of the amplifier from Part c), also having an input voltage range from 0-5 V. i) Calculate the number of discrete input levels which can be recognised. Calculate the input resolution of the ADC in volts. ii) (8 marks) (2 marks) (6 marks) (2 marks) (2 marks)
