Some key functions of an Air Limit Sensor in a cotton picker include:

1. Monitoring air pressure levels: The sensor continuously monitors the air pressure within the pneumatic systems of the cotton picker, such as the air ducts or tubes used for cleaning or conveying cotton. It ensures that the air pressure remains within the desired range for efficient operation.

2. Controlling airflow: Based on the data received from the Air Limit Sensor, the control system of the cotton picker can adjust the airflow by regulating the operation of fans, blowers, or valves. This helps to ensure proper airflow to optimize the performance of the machine during cotton picking and processing.

3. Preventing system malfunctions: The Air Limit Sensor helps prevent potential malfunctions or damage to the pneumatic systems of the cotton picker by detecting abnormalities in the airflow. If the sensor detects issues such as air leaks or blockages, it can trigger alerts to prompt maintenance or repairs before serious problems occur.
