Problems solved by technology
The existence of "background voltage" / "noise floor" makes it more difficult to detect such small voltage changes
When the "background noise" / "floor noise" is too large, it will not even be able to detect effective signals

The invention discloses working solution metal particle detection equipment, which comprises a signal processing module, a first excitation coil, a second excitation coil and anintermediate feedback coil, wherein the first excitation coil, the second excitation coil and the intermediate feedback coil are arranged at a working solution pipeline. The first excitation coil generates a first magnetic field, the second excitation coil generates a second magnetic field, the magnetic field direction of the second magnetic field at a neutral point between the first excitation coil and the second excitation coil is opposite to the magnetic field direction of the first magnetic field, the intermediate feedback coil is arranged at the neutral point, a superimposed magnetic field of the first magnetic field and the second magnetic field is induced to induce and generate an induction signal; and the signal processing module is used for generating an output signal indicating whether the metal particles exist or not and indicating the sizes of the metal particles according to the amplitude of the induction signal of the intermediate feedback coil.
Description
technical field [0001] The invention relates to metal particle detection technology, in particular to a working fluid metal particle detection device and a coil manufacturing method thereof. Background technique [0002] For products with worn metal parts such as gears, real-time detection of gear wear can effectively ensure product performance. When the product is lubricated or cooled by oil, metal particle detection equipment can be installed in the liquid circuit. Specifically, a feedback coil and a symmetrical excitation coil are installed on the liquid circuit pipeline. When the coils pass through, the magnetic field between the excitation coil and the feedback coil will change, which will lead to a change in the induced voltage on the feedback coil. Therefore, according to the change in the induced voltage of the feedback coil, it can be judged whether there are metal particles passing through, and then judge Whether there is component wear. [0003] However, in actu...
