PURPOSE:To enhance the detection accuracy of the wt. value of an object, by constituting the title detector of a turntable for mounting an object, a wt. detection element for detecting the wt. of the object placed on the turntable and a circuit part for processing the signal from the wt. detection element. CONSTITUTION:This detector is constituted of a turntable mounting an object 2, a wt. detection element 5 detecting the wt. of the object mounted on the turntable and a circuit part 6 for detecting the wt. of the object on the turntable n-times during one revolution of the turntable by the wt. detection element to successively average (n)-detected wt. values. By this constitution, the wt. of the object on the turntable can be detected while the turntable is rotated. The wt. of the object is detected n-times during one revolution of the turntable and (n)-detected wt. values are successively averaged to obtain a wt. value. By this method, even when there is an intercardinal error in a weighing mechanism, the wt. of the object can be accurately detected. Further, since (n)-accurate wt. values per one revolution are obtained, an S/N ratio is high and wt. change can be instantaneously detected.
