A Paddle is rotated slowly by a stepper motor. An encoder coupled to the paddle shaft produces electrical pulses during its rotation. The pulses are monitored by a microprocessor to ascertain its movement. Paddle rotation stops when the material covers it. The microprocessor signals the material presence and sends the result in the form of potential free contacts. The microprocessor starts the motor periodically to check the material presence. The paddle flaps and vibrates to discard the clinging material ensuring the material has receded and paddle is now clean. Thereafter the output status is changed and motor starts rotating smoothly again waiting for the level to come.
