A restorable cable-type temperature difference and sensing detector consists of a microcomputer modulator and a temperature sensing cable, and a terminal processor. The detector is characterized in that the temperature sensing cable in the detector is composed of a line-type temperature sensing component C and a line-type temperature sensing component D, which can generate two same equivalent electric parameter signals. The electric parameter signals can be voltage, resistance, capacitance, etc. When the temperature rising speed reaches or exceeds 10 Celsius system / min, the electric parameter values of the line-type temperature sensing component C and D have unequal changes, since the temperature sensing component C or D with external protection layer or heat insulation layer has the different heat transmission coefficient with the sensing component C or D without external protection layer or heat insulation layer. If the absolute difference between the two electric parameters collected by the microcomputer modulator is above or equal to the preset value, the detector will send alarm signals to realize alarm of temperature difference.
