Abstract

According to one embodiment of the present disclosure a thermocouple is provided that includes an electrical component, such as a resistor, at or in close proximity to a junction where the temperature is expected to be measured. By monitoring analog voltage measurements, the system determines, for example, whether the measured temperature actually represents a temperature reading at the junction or whether the thermocouple has been compromised due to one or more of a variety of health issues, such as, a short circuit in the thermocouple, thereby causing a false junction.
