4. Industrial Sensors

Sensors are essential components in industrial automation systems. They monitor various variables like temperature, pressure, proximity, humidity, and flow, providing real-time data that can be used to control machinery or alert operators to potential issues. Sensors are integrated into many types of equipment to enhance precision and performance.

Types of Sensors:

Proximity Sensors: Detect the presence or absence of objects.

Temperature Sensors: Monitor the temperature of machinery or the environment.

Pressure Sensors: Used to measure the pressure within systems like hydraulic pumps or gas lines.

Flow Sensors: Measure the flow rate of liquids or gases in pipes.

Uses:

• Monitoring temperature and pressure in a chemical plant.
• Ensuring product quality in food and beverage production.
• Detecting object movement or position in robotic systems.

5. Automated Guided Vehicles (AGVs)

Automated Guided Vehicles (AGVs) are mobile robots that transport materials or products within a facility without human intervention. They follow predefined paths using sensors, cameras, or magnetic strips. AGVs are increasingly popular in warehouses and distribution centers as they help to automate the movement of goods from one place to another.

Types of AGVs:

Towing AGVs: Used to pull carts and trailers across the facility.

Unit Load AGVs: Designed to transport individual loads, such as pallets or boxes.

Forklift AGVs: These AGVs can lift and move pallets or other materials.
