するブリツジ断線検出回路。 A pair of output lines are taken out from a bridge circuit made up of a strain gauge and to which a predetermined DC voltage is applied, a differential amplifier to which the output lines are connected, and the amount of distortion of the strain gauge by the output of the differential amplifier. In the detection circuit, one of the pair of output lines is directly connected to the detection device, and the detection device has a first threshold value and a second threshold value.
A threshold value is set, and when one output of the pair of output lines deviates from the threshold width determined by the first threshold value and the second threshold value, it is determined that the bridge circuit is disconnected. A bridge disconnection detection circuit characterized in that:
