| Abstract | 本实用新型公开了一种法兰式液态金属转速传感器，所述法兰式液态金属转速传感器包括绝缘的外壳轴筒、测速转子、密封端盖和法兰密封端盖；外壳轴筒套设于测速转子上，密封端盖和法兰密封端盖分别固定于外壳轴筒和测速转子轴向相对的两端，以形成密封的测速腔体，测速腔体内存储有液态金属；外壳轴筒上设置有感应电极，测速转子上设置有输入电极；感应电极和输入电极浸入液态金属，且分别连接同一测速电路；当进行测速时，电流经所述输入电极流入液态金属，且在输入电极与感应电极同向相对时，经感应电极输出一电流脉冲信号至测速电路。进而有效提升了法兰式液态金属转速传感器的安全性和稳定性。 |
| Other Abstract | The utility model discloses a flange type liquid metal rotating speed sensor. The flange type liquid metal rotating speed sensor comprises an insulating shell shaft barrel, a speed measuring rotor, asealing end cover and a flange sealing end cover, the speed measuring rotor is sleeved with the outer shell shaft barrel, the sealing end cover and the flange sealing end cover are fixed to the two opposite ends of the outer shell shaft barrel and the speed measuring rotor in the axial direction respectively to form a sealed speed measuring cavity, and liquid metal is stored in the speed measuringcavity. An induction electrode is arranged on the shell shaft barrel, and an input electrode is arranged on the speed measuring rotor; the induction electrode and the input electrode are immersed into liquid metal and are respectively connected with the same speed measuring circuit; when speed measurement is carried out, current flows into the liquid metal through the input electrode, and when the input electrode and the induction electrode are opposite in the same direction, a current pulse signal is output to the speed measurement circuit through the induction electrode. And the safety andthe stability of the flange type liquid metal rotating speed sensor are effectively improved. |
