  • Apparatus and method for detecting electrical resistance change in connectors to a remote mounted sensor
    Patent number: 6198295
    Abstract: A control system detects an electrical resistance change in a connector coupling a remote mounted temperature sensor to a control system. A control system determines the resistance of the sensor or the connector by selectively charging or discharging a capacitor through a unidirectional circuit element or the sensor. The control system is disclosed as controlling a water heater system, although such control systems may be used to control other systems using remote mounted sensors. A calibrating circuit is used to measure a transient response of an RC circuit, from which resistance can be derived.
