Common applications for PID control:
Flow control: Use a flow sensor to feedback the flow data and perform accurate flow control.
Pressure control: Use a pressure sensor to feedback the pressure data and perform precise
pressure control.
Air volume control: Use an air volume sensor to feedback the air volume data to achieve
excellent air volume regulation.
Temperature control: Use a thermocouple or thermistor to feedback temperature data for
comfortable temperature control.
Speed control: Use a speed sensor to feedback motor shaft speed or input another machine
speed as a target value for synchronous control.
