<p>PURPOSE:To detect the abnormality of an electric device with a comparatively simple constitution and to improve the reliability of a sensor and a control system by using two output values having respectively different dimensions. CONSTITUTION:The abnormality detector is provided with an integration circuit 1, a differential amplifier 2 and a coincidence discriminating circuit 3 to set up two output values having respectively different dimensions to the same dimension on the basis of differentiation and integration so that these two output values can be compared at their capacity. The abnormality of the electric device generating both the output values is detected on the basis of said comparison. Consequently, it is unnecessary to constitute an ordinary redundant system and the abnormality detector can be obtained with the comparatively simple constitution.</p> |
