Abstract:
    The invention is concerned with the design method of the combined temperature sensor, including the protecting sleeve, the platinum resistance, the thermistor, the connecting line, the measuring circuit, and the microprocessor. The sensor samplings the measure result of the platinum resistance and the thermistor when it works. The platinum resistance with stable capability and good linearity during the steady state demarcates the thermistor, which solves the shortage of the thermistor that is low dispersing and re-existing; the platinum resistance uses the character of the thermistor that is rapid reaction and high delicacy to conquer the shortage of big time-constant when the ambient temperature changes acutely.
