Figure 4 shows the automated filling station. Based on the machine operation answer following questions. [Rajah 4 menunjukkan stesen pengisian automatik. Berdasarkan operasi mesin, jawab soalan-soalan berikut.] (i) Suggest suitable sensors that can be installed at locations A, B, C and D. Describe the operation and function for each suggested sensor. [Cadangkan penderia-penderia yang sesuai dipasang di lokasi A, B, C dan D. Terangkan operasi dan fungsi untuk setiap penderia yang dicadangkan.] (8 Marks/Markah) (ii) In location B, 1 to 10 V analogue sensor used to measure the height of liquid. The sensor will produce analogue voltage between 7.55 to 7.60 V for correct liquid volume. Estimate the Analog to Digital Conversion (ADC) range in 10- bit produced by PLC when it receives the input voltage from sensor.
