TL;DR: In this article, the authors present a CONDITION MONITORING system for detecting and detecting failures in a continuous-time monitoring system, which includes a series of interconnected circuits.
Abstract: A CONDITION MONITORING SYSTEM HAVING MEANS FOR SENSING AND INDICATING FAILURES IN THE COMPONENTS OF THE SYSTEM. THE SYSTEM INCLUDES A SERIES CIRCUIT INCLUDING ONE OR MORE IMPEDANCES AND AT LEAST ONE VARIABLE IMPEDANCE SENSING ELEMENT. MEANS FOR PRODUCING A SIGNAL RESPONSIVE TO THE MONITORED CONDITION IS CONNECTED ACROSS ONE OF THE IMPEDANCES AND IS RESPONSIVE TO THE IMPEDANCE OF THE SENSOR. A SECOND SIGNAL PRODUCING MEANS IS CONNECTED ACROSS TWO JUNCTIONS OF THE CIRCUIT AND IS RESPONSIVE TO OPERATIONAL CHANGES WHICH MAY OCCUR IN THE COMPONENTS OF THE SYSTEM. A THIRD SIGNAL PRODUCING MEANS COMBINES THE FIRST TWO SIGNALS TO PROVIDE A SIGNAL WHICH IS RESPONSIVE TO BOTH THE MONITORED CONDITION CHANGES AND OPERATIONAL CHANGES IN TEH SYSTEM COMPONENTS.
