Abstract
According to one embodiment, an apparatus for reading a temperature of a material includes a thermistor that is communicable in temperature sensing communication with the material. The apparatus also includes a first resistor that has a first resistance and a second resistor that has a second resistance that is lower than the first resistance. Additionally, the apparatus includes a switch that is selectively controllable to electrically couple the first resistor and second resistor to the thermistor in a low temperature mode. The switch also is selectively controllable to electrically couple the second resistor to the thermistor and electrically decouple the first resistor from the thermistor in a high temperature mode.
