The present disclosure is directed to a temperature detector for detecting a temperature of a component. The temperature detector may receive a first signal indicative of the temperature of the component, with the first signal being received from a first type of temperature sensor. The temperature detector may further receive a second signal indicative of the temperature of the component, with the second signal being received from a second type of temperature sensor different from the first type of temperature sensor. The temperature detector may combine the first and second signals to generate an output indicative of the temperature of the component.
