摘要 |
<p>A reference voltage generating circuit (11) is constituted by resistors (RE) and (RF) each having a resistance not influenced by an application of pressure. The reference voltage generating circuit (11) is connected between one and the other ends of a bridge circuit. A failure judgement of the bridge circuit is performed based on a comparison of a voltage difference (VBC) between two midpoints (B, C) of the bridge circuit and voltage differences (VCE, VBE) between a reference voltage level of the reference voltage generating circuit (11) and the voltage levels of two midpoints (B, C). <IMAGE></p> |
