The utility model discloses a high-precision bridge for measuring temperature of a constant-temperature cylinder. The high-precision bridge for measuring temperature of a constant-temperature cylinder comprises a constant-temperature cylinder, wherein thread slots are uniformly disposed in an outer surface of the constant-temperature cylinder, and thus the constant-temperature cylinder with the thread slots forms a uniform temperature layer; resistance wires which serve as a bridge are wound in the thread slots; and the resistance wires which serve as the bridge are connected with wiring electrodes. The high-precision bridge for measuring temperature of the constant-temperature cylinder, through arrangement of resistance wires in the thread slots, realize an effect of overall uniform temperature which is needed during temperature measurement, and further, since temperature measuring sensors and the uniform temperature layer are in tight contact, a minimum heat echelon and excellent temperature-sensing effects
