Embodiment Construction

[0087] It should be noted that the impedance values ​​shown in the figures are given in Ohms.

[0088] Such as figure 1 As shown, the device for detecting impurities in a fluid comprises: a set of fluid measuring electrodes 11 generally spaced apart by 1.6mm, and a set of ferrous wear particle detecting electrodes 12 generally spaced apart by 0.6mm. Such as Figure 13 These electrodes are located in the fluid flow in the adapter housing 13 as shown.

[0089] The fluid measurement electrode 11 is much larger than the ferrous particle detection electrode 12 and is located upstream of the ferrous particle detection electrode 12 .

[0090] The iron-containing particle detection electrodes 12 are also parallel and aligned at right angles to the axis of the alignment of the fluid measurement electrodes 11 .

[0091] The ferrous particle detection electrode, which is much smaller than the fluid measurement electrode 11 , is located in the smaller fluid cavity 14 of the adapter 13 ...

Abstract

A method for detecting extraneous matter in a fluid including the steps of applying an energy source to electrodes located in a fluid, measuring real and imaginary electrical impedance values across the electrodes for a plurality of different frequencies of alternating energy and identifying at least one characteristic of an extraneous matter in the fluid.

Description

technical field [0001] The present invention relates to the analysis of fluids such as oil. The invention particularly relates to monitoring fluid quality for impurities such as dirt. Background technique [0002] It has been estimated that repairs and downtime caused by oil-related engine or other machine failures account for approximately 30-50% of operating costs in the Australian mining industry. In the economies of developed countries, losses due to wear and tear of machinery and engines account for approximately 6% of the gross national product. Thus, it is of substantial importance to develop effective techniques for reliable prediction of wear and maintenance of the effectiveness of operating lubricants. Current diagnostic tests based on pre-scheduled oil sampling cannot quickly detect rapidly progressing component failures or sudden ingestion of oil impurities. [0003] Furthermore, in many cases, the timing of any oil changes is related to the measured use of th...
