    摘要: The present invention relates to an angle sensor temperature correcting device, in particular to obtain a superior correction result at a low cost without requiring expensive equipment for recording in advance and without requiring excessive screening. A ratio ± between a bridge midpoint potential difference offset Cref and a voltage Sref across power supply terminals of a bridge, at a reference temperature (± = Cref/Sref) is stored in a memory 18-4 as a zero correcting factor. A voltage St across the bridge power supply terminals at a given time is multiplied by the zero correcting factor ± to calculate a current temperature-corrected bridge midpoint potential difference offset Ct (Ct = St €¢ a), to correct opening information obtained from a bridge midpoint potential difference Vt at the current time.
