Fundamentals of Automation

What is the primary function of a sensor in industrial automation?

• To provide power to industrial machines.

• To detect and measure physical properties in industrial processes.

• To control the speed of production lines.

• To store data from industrial processes.

How do actuators convert electrical signals into physical movement?

• Actuators convert physical movement into electrical signals using sensors.

• Actuators convert electrical signals into physical movement by using mechanisms that transform electrical energy into mechanical energy.

• Actuators rely solely on hydraulic pressure to function.

• Actuators generate heat to create movement in mechanical systems.

Name two types of sensors commonly used in automation systems.

• Pressure sensor

• Temperature sensor, Proximity sensor

• Light sensor

• Motion sensor

What role do limit switches play in automation processes?

• Limit switches are used to increase the speed of automation processes.

• Limit switches are primarily for power supply management in automation.

• Limit switches are only necessary for manual operations, not automation.

• Limit switches play a crucial role in detecting positions and providing feedback in automation processes.

Explain the difference between analog and digital sensors.

• Analog sensors provide continuous signals, while digital sensors provide discrete signals.

• Digital sensors can only measure temperature, while analog sensors can measure various parameters.

• Analog sensors are always more accurate than digital sensors.

• Analog sensors use binary signals, while digital sensors use continuous signals.
