Question 1 Report

A company uses a computer-controlled system to fill bottles on a production line.

(a) Describe the role of the following components in this system.

Component	Role in the bottle-filling system
Sensor
Microprocessor
Actuator

[3]

(b) Give two advantages of using a computer-controlled system for this task. [2]

Answer

Answer Details

(a)

Component	Role in the bottle-filling system
Sensor	Detects when a bottle is in position directly under the filling nozzle, or measures the current fill level of the bottle. [1] Without the sensor, the system would not know when to start or stop filling.
Microprocessor	Receives the data from the sensor, compares it with the target fill level, and sends appropriate control signals to the actuator. [1] It is the decision-making component of the system.
Actuator	Opens or closes the valve that controls the flow of liquid into the bottle. [1] It translates the microprocessor's electronic signals into a physical action.

(b) Two advantages of a computer-controlled filling system:

The fill level is consistent and accurate for every bottle, ensuring uniformity across the entire production run. [1]
The process is faster than manual filling and can operate continuously without breaks, increasing production output. [1]
