The invention relates to a non-contact dynamic torque rotating speed monitoring device and method. The device comprises a mandrel; the mandrel is connected with the twisting sleeve; the mandrel and the twisting sleeve are arranged in the sleeve in a penetrating manner; the twisting sleeve is provided with at least two gears, and the gears have the magnetic conduction characteristic. A fixing groove is formed in the position, located on the gear, of the sleeve and communicated with the twisting sleeve, a circuit board is placed in the fixing groove, a Hall element corresponding to the gear is arranged on the circuit board, an air gap is formed between the Hall element and the gear, and magnetic steel is arranged on the side, opposite to the gear, of the Hall element. According to the invention, the signal transmission does not need a wire or a metal conductor, the abrasion problem is avoided, the quality is stable, and the cost is reduced. 本发明涉及一种非接触式动态扭矩转速监测装置及监测方法，包括：芯轴；扭套，所述芯轴和扭套相连；套筒，所述芯轴和扭套穿设在套筒内；所述扭套上设置有
