The paddle installed on the main shaft of the anti-rotation level switch relies on the power of the internal motor to continuously rotate. When the detected
object does not apply load to the blade,
The paddle blade is constantly rotating, but when the paddle blade stops rotating due to the load brought by the detected object, the motor will also stop
rotating.
The contact output is triggered at the same time. At this time, in order to protect the motor, a device that automatically cuts off the power of the motor is
provided.
In addition, when the force preventing the motor from rotating disappears, it will re-rotate by restoring the power to the motor, and the contact output will be
switched at the same time.
Through the above operations, the presence or absence of the detected object can be detected.
