ABSTRACT:
An apparatus and method is disclosed for sensing a full level condition for a large basket. A signal generator produces an oscillating signal which is applied to energy emitters that are capable of transmitting electrical energy along defined paths and across the width of the large basket. The transmitted electrical energy is received by a plurality of receivers which output an electrical signal which is representative of the signal applied to the energy emitters when material which is being loaded into said basket does not interfere with the energy being transmitted along the defined paths. A logic circuit analyzes the signals output from the receivers and produces a status signal indicating whether material which is being loaded into the large basket has interfered with the energy being transmitted along the defined paths.
