How do Sensors, Transducers and Actuators work?

How Sensors, Transducers and Actuators work Sensors, transducers and actuators are elements of the automation system at level 1, which is the lowest level of the automation system. Just like the human body system, where humans have five senses or five sense systems, namely the sense of taste, the sense of sight, the sense of hearing, the sense of touch, the sense of smell, the function of the sensors & transducers in the automation system is to sense physical quantities that are important for a process. or often referred to as process parameters.

How Sensors, Transducers and Actuators work

Sensors, transducers and actuators are elements of the automation system at level 1, which is the lowest level of the automation system. Just like the human body system, where humans have five senses or five sense systems, namely the sense of taste, the sense of sight, the sense of hearing, the sense of touch, the sense of smell, the function of the sensors & transducers in the automation system is to sense physical quantities that are important for a process. or often referred to as process parameters.

The process parameters can be in the form of pressure, flow, level, temperature, weight, specific gravity, mention all physical quantities / parameters that are potentially important parameters in the manufacturing process or production process. This physical quantity is sensed and processed by the 2nd level of the automation system hierarchy, namely the Sensor and Actuator system / control system. The input quantities in most control systems are not electrical quantities, such as physical, chemical, mechanical quantities and so on.

To apply electrical quantities to the measurement system, control system, usually non-electric quantities are first converted into an electrical signal through a device called a transducer. Control system / sensor and actuator system (level 2 automation system hierarchy) after processing the input (input) from the sensor transducer, provides output (output) usually in the form of a driving signal to the actuator (driver).
