Abstract

The parameter value limit, sensing apparatus comprises two sensors which are arranged to provide respective warning signals. Logic means including a validation circuit are connected to the sensors, and arranged to provide a parameter beyond limit signal only when both the sensors provide a warning signal. A further sensor may be included to provide a warning signal when the parameter lies beyond a specified value, the logic means then comprising three validation circuits each of which is connected to a respective pair of sensors and each providing a parameter beyond limit signal only when both of its pair of sensors provide a warning signal.
