ABSTRACT:
A temperature sensing circuit including a temperature sensing element located at a medium to sense the temperature of the medium. The sensing element is a resistive element with a range of resistive values corresponding to a range of sensed temperatures. The sensing element is connected to circuitry for detecting variations of the resistance of the element. The circuitry provides an output signal of one state when the element resistance increases beyond a first value and provides an output signal of a second state when the element resistance decreases beyond a second value.
