Sensors and actuators track different signals, operate in different ways, and must work together to get the job done.They are also physically located in different areas and are often used in single ** applications.
1. Input and output
The sensor looks for input from the environment that triggers a specific action.Actuators, on the other hand, track the output of the system and the machine.
2. The electrical signal
Sensors use electronic signals to read specific environmental conditions and perform assigned tasks.However, the actuator measures heat or motion energy to determine the effect.
3. Rely on
Sensors and actuators can actually rely on each other to perform specific tasks.If both are present, the actuator will rely on the sensor to do its job.If one or both fail, the system will fail.
4. Switch directions
Sensors tend to convert physical properties into electrical signals.Actuators do the opposite: change electrical signals into physical ones.
If there are both sensors and actuators, one is on the input port and the other is on the output port.
Sensors are commonly used to measure asset temperature, vibration, pressure or liquid level.Industrial applications of actuators include operating dampers, valves, and couplings.
