<p><P>PROBLEM TO BE SOLVED: To provide a failure diagnostic device of a conveyor scale capable of easily and accurately determining that a failure has occurred in load cells and a weighing part in operation, and easily recovering to perform normal weighing. <P>SOLUTION: A conveyor scale includes load signal output means for adjusting and outputting a load signal of one of two load cells 7, 9; 8, 10 provided at the left or right in a moving direction of a conveyor 2 and two half bridge load signals of the other strain-gauge load cells, a total of three load signals, or two half bridge load signals of each of the two strain-gauge load cells, a total of four load signals, so that each load signal is changed to be almost the same size with respect to the same load applied to the load cells. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
