Design of the Microfluidic Chip of Oil Detection
Wear debris in hydraulic oil causes most of the faults of hydraulic system and is also an important information carrier, so it is essential to check the condition of wear debris in hydraulic oil. On the basis of inductive principle and microfluidic chip technology, the design of a microfluidic chip of oil detection is presented in this paper. the relation between coil geometry parameters and inductive change of planar inductor are analyzed through the related experimental statistics, the result being that when the ferrous metallic particle flows through planar inductor, the measured inductance variation increases with the number of turns and decreases with the coil line width.
