Automated Systems Flashcards
What is a sensor?
A sensor is a device that detects and measures the physical properties of the environment, then converts it into readable signals.
What are the key features of signals? and describe them.
Sensitivity: Ability to detect small changes in the environment, like light, pressure or temperature.
Accuracy: The ability to provide precise measurements for consistent and reliable data.
Resolution: Creates parameters for which the smallest change it can detect.
Range: The span or area that the sensor can accurately measure.
Response Time: The speed at which the sensor reacts to changes.
Name 6 Types of sensors and explain them.
Temperature sensors: Measure thermal energy to give temperature readings.
Pressure sensors: Detects the force exerted on the surface.
Light sensors: Measure light intensity.
humidity sensors: Determine the amount of moisture in the air.
Flow level sensors: Monitor the flow and level of liquids.
Gas sensors: measure the concentration of gasses in the air.
Give an industrial application of sensors.
Distributed control systems (DCS)
Give a common application of sensors.
Smart Lighting systems, Weather Stations, Motion capture Devices
What is the role of the microprocessor in the automation process
Data Storage, Processing Input Data, Generating Output, Automated, Decision Making and Operational Control.
but its main function summarized is that is processes instructions and manages the flow of data within a computer system.
What is an actuator?
An actuator is a device that preforms actions or controls a mechanism in the system, translating electrical signals into physical movement.
What are some of the things that an actuator can do?
Automatic shutdowns and operate water and gas pumps to control the flow.
What are some industrial applications of actuators?
Actuators are widely used in industrial systems to control machinery and processes
What are the types of actuators?
- Electrical actuators
- DC servomotors
- AC motors
- Stepper motors
- (solenoids) - Hydraulic actuators
- use hydraulic fluid to amplify the controller command signal. - Pneumatic actuators
- use compressed air as the driving force
