Iron wear particle content measurements in process liquids using micro channel - Inductive method

A detection chip is designed and manufactured to study the relationship between iron wear particle content in hydraulic oil and the detected variation of average inductance, which detects content of iron wear particle by means of micro channel - inductive. Through experiments, we obtained inductive values in the cases. The case is that the sizes of iron wear particle are the same, while the content of iron wear particle are different. Thus the curve between content of iron wear particle content and variation of average inductance was drawn. Experimental results show that the inductance value increases with the increase of the iron wear particle content in hydraulic oil. Experiments prove that the way is feasible for the detection of iron wear particle content in hydraulic oil. This study has an important significance for the realization of iron wear particle content detection in hydraulic oil.
