Thermistor high resistance lead temperature sensor production method and interference-free temperature sensor

The preparation method for a kind of heat sensitive resistance high resistant lead temperature sensor and the undisturbed temperature sensor are provided in invention. The method is: making the carbonfiber material and making the carbon fasciculi; treating the carbon fasciculi surface and getting the carbon fiber lead; connecting one end of the carbon fiber lead and the heat sensitive resistance,the other is connected with the copper lead; treating the surface of the lead corner of carbon fiber lead, heart sensitive resistance and the adhesive point of copper lead; the other end of the carbon fiber high resistant lead is connected with the two input pipe feet of computing amplifier, the constant-current source and ground through copper lead. The output of computing amplifier is the output of the temperature sensor; the out of carbon fiber high resistant lead is covered with the sealing protection coat; the heat sensitive resistance and the copper lead connecting the constant-currentsource and the computing am
