ABSTRACT:
Apparatus and method apparatus for detecting marginal gradation changes of a controlled product on a conveyor. The apparatus comprises a transducer (4) for converting swinging motion to a number of pulses; a member (24) operably secured to the transducer, the member for being in contact with the controlled product to cause the member to swing back and forth, thereby causing the transducer to generate the number of pulses; and a programmable device (28) operably connected to the transducer, the device being adapted to count the number of pulses generated by the transducer over several blocks of time periods, compare the number in each block of time to a group of reference numbers for the product, sum the number of occurrences that the number is above or below the group of reference numbers and provide an indication when the sum exceeds a target value.
