electronic sensors and actuators
The computer control system has to be able to do two things. It has to make things happen and it needs to know what is happening. Sensors on the production line provide information to the computer system about what is happening. Actuators are used to make things happen.
On the Cadbury production lines there are a variety of actuators including electric motors, pneumatic valves, solenoids, lights and sirens.
The production line is monitored using sensors, including for pressure, mass, temperature, the presence of objects, counting of objects and metal detection.
