Embodiment Construction

[0009] Below in conjunction with Fig. 1, describe in detail the concrete work situation that the present invention proposes, figure 1 , the oscillating coil (2) is placed in the oil pool (1), the detection oscillator (3) is electrically connected to the oscillating coil (2), the reference oscillator (4) and the detection oscillator (3), and the difference frequency digital segment The device (5) is electrically connected, and the difference frequency digital segmenter (5) is electrically connected to the display alarm (6).

[0010] An inconvenient reference oscillation frequency is generated by the reference oscillator (4) and sent to the difference frequency digital segmenter (5). At the same time, the oscillation circuit formed by the detection oscillator (3) and the oscillation coil (2) also generates an oscillation frequency corresponding to the reference The same frequency signal as the oscillator is also sent to the differential frequency digital segmenter (5). When the ...

Abstract

The invention relates to a difference frequency electric field detector of lubricant metal impurities. When the lubricant metal impurities in a lubricant pool are detected to reach a certain degree, the induction of an oscillating coil is changed, the oscillating frequency of a detection oscillator is changed, the change is displayed through a display alarm through segmentation of a difference frequency digital sectionalizer and then is alarmed, and the quality of a lubricant is analyzed.

Description

technical field [0001] The invention is a differential frequency electric field detector for lubricating oil metal impurities in the detection technology field. When the lubricating oil metal impurities in the oil pool reach a certain level, the inductance of the oscillating coil changes, so that the oscillating frequency of the detection oscillator also occurs. Changes, through the division of the differential frequency digital segmenter, it is displayed from the display alarm and alarmed, so as to understand the quality of the lubricating oil. Background technique [0002] At present, the ordinary scale does not detect the performance of lubricating oil, but can only detect the amount of lubricating oil in the engine, and cannot see any parameters related to lubricating oil. Contents of the invention [0003] The object of the present invention is to provide a difference-frequency electric field detector for metal impurities in lubricating oil, which generates an inconve...
