Abstract

PURPOSE:To realize a detection of fault over a wide range, by installing a polarity inverter at the side of a detector to transmit a noninverse signal and an inverse signal alternately to the side of a processor and then deciding a normal state when the result of addition of said two signals is substantially zero. CONSTITUTION:The analog signal detected by a detector 1 is supplied to a switching circuit 10 in the form of the 1st analog signal AS1 of a noninverse signal and the 2nd analog signal AS2 of an inverse signal and then converted into the digital signals DS1 and DS2 through an A/D converter 2 to be delivered through a transmitter 5. A discriminator 12 adds the output of detector 1 to the data stored in the storage circuit 11 after a sampling to decide whether the result of addition is close to zero or not.
