<p><P>PROBLEM TO BE SOLVED: To provide a conveyor scale capable of easily and accurately determining that a zero-point or span error has occurred in output from any one of two half bridges in operation, and correcting the output even in operation to continue the operation. <P>SOLUTION: A conveyor scale includes half bridge load signal output means for adjusting and outputting two half bridge load signals generated on the basis of output signals from two terminals in a Wheatstone bridge circuit composed of at least four strain gauges affixed to a strain part of a load cell so as to be almost the same size of load signals with respect to the same load applied to the load cells. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
