Abstract
A load detection device for detecting a load, based on a differential signal output from a load cell including an excitation-side differential amplifier circuit for amplifying an excitation signal to be transmitted to the load cell, a measurement-side differential amplifier circuit for amplifying a first differential signal output from the load cell, and a control device for controlling the circuits. The control device executes a gain adjustment process of adjusting an output gain by selecting an excitation-side gain by the excitation-side differential amplifier circuit and a measurement-side gain by the measurement-side differential amplifier circuit such that a measurement value measured based on a second differential signal output from the measurement-side differential amplifier circuit falls within a predetermined range. The gains are selected from among candidate excitation-side gain values set at predetermined intervals as the excitation-side gain and candidate measurement-side gain values set at predetermined intervals as the measurement-side gain.
