Question 2 a) A linear liquid-level control system has input control signal of 2 to 15 V is converts into displacement of 1 to 4 m. (CLO1) i. Determine the relation between displacement level and voltage. [5 Marks] ii. Find the displacement of the system if the input control signal 50% from its full-scale b) A PT100 RTD temperature sensor has a span of 10°C to measurement results in a value of 90°C for the temperature. Specify the accuracy is: (CLO1) [3 Marks] 200°C. A the error if i. ±0.5% full-scale (FS) [4 Marks] ii. ± 0.3% of span [4 Marks] iii. ±2.0% of reading [4 Marks] c) A controller output is a 4 to 20 mA signal that drives a valve to control flow. The relation between current, I and flow, Q: Q = 30 [/- 2 mA] ¹ liter/min. i. What is the flow for 15 mA? [2.5 Marks] ii. What current produces a flow of 1 liter/min? [2.5 Marks]
