Abstract
The utility model discloses a plane inductance type abraded particle monitoring device and a measuring unit thereof. The device comprises a measuring unit and an analyzing unit, wherein the measuring unit comprises a plane inductor and a cavity body through which liquid to be measured flows, and taps at both ends of an inductance coil of the plane inductor are connected with the analyzing unit; and the inductance coil of the plane inductor is used as part of the inner wall of the cavity body. When the plane inductance type abraded particle monitoring device provided by the utility model is applied to the monitoring of abraded particles in oil liquid or other liquid to be measured, the cavity body is used as a flow passage of the liquid to be measured. Because the liquid to be measured directly contacts with the inductance coil of the plane inductor, the theoretical distance between the liquid to be measured and the inductance coil of the plane inductor is 0, so that more magnetic lines of force can pass through the abraded particles in the liquid to be measured, and the change of the inductance quantity of an insulated conducting wire is larger so as to greatly enhance the monitoring sensitivity. The plane inductance type abraded particle monitoring device and the measuring unit thereof have an important meaning to the fault detection and the fault diagnosis of machinery equipment.
