Abstract	本实用新型公开了一种法兰式磁流体转速传感器，所述传感器包括壳体及设置在该壳体上的下端盖与安装有法兰盘的上端盖；还包括设置在壳体上用于感应并记录测速电路中的电流通断次数的感应电极；设置在壳体上并贯穿该壳体以及所述上端盖、下端盖的测速轴；以及设置在壳体内用于通过电流通断次数来测量所述测速轴转动圈数的测速转子；所述测速转子包括套筒以及设置在该套筒上的装载有测速电路的输入电极；所述上端盖、下端盖与壳体之间形成一用于进行测速的测速腔体，测速腔体具有一定间隙，该间隙中设置有用于控制传感电路通断的带有非磁性导电颗粒的磁流体，以达到提高磁流体转速传感器的响应速度、稳定性、可靠性以及经济性。
Other Abstract	The utility model discloses a flange type magnetofluid rotating speed sensor. The sensor comprises a shell, a lower end cover arranged on the shell and an upper end cover provided with a flange plate.The induction electrode is arranged on the shell and is used for inducting and recording the on-off times of current in the speed measuring circuit; the speed measuring shaft is arranged on the shelland penetrates through the shell, the upper end cover and the lower end cover; the speed measuring rotor is arranged in the shell and is used for measuring the number of turns of rotation of the speed measuring shaft through the number of times of current on-off; the speed measurement rotor comprises a sleeve and an input electrode which is arranged on the sleeve and loaded with a speed measurement circuit; a speed measuring cavity used for measuring speed is formed among the upper end cover, the lower end cover and the shell, a certain gap is reserved between the speed measuring cavity and the shell, and magnetic fluid with non-magnetic conductive particles is arranged in the gap and used for controlling on-off of a sensing circuit, so that the response speed, stability, reliability andeconomical efficiency of the magnetic fluid rotating speed sensor are improved.
