Abstract

PURPOSE:To securely detect trouble such as the breaking of a wire by interposing a deforming circuit which deforms the mutual polarity voltage of an AC noise signal inputted to a signal line asymmetrically on the way of the signal line. CONSTITUTION:The T-shaped circuit consisting of resistances R6 and R7 is interposed between input signal lines S1 and S2 in parallel, and the deforming circuit 10 are inserted in parallel to the resistance R7, i.e. the input signal lines S1 and S2. Here, the deforming circuit 10 consists of a series circuit formed by connecting diodes 11 and Zener diodes 12 in opposite directions. Consequently, when a voltage amplified by a DC amplifier 1 is integrated by an A/D converter, the integral value of components of an AC noise signal is a plus finite value and a constant is so set that the value exceeds a threshold value, thereby securing burnout detection.
