Unwanted metal particles in
industrial fluids can damage machinery and equipment that operate with these
fluids. These particles can have a frictional and abrasive
effect on machine parts, especially those with precise tolerances, causing
corrosion, premature wear and breakdown of machines. In this study, a magnetic
sensor prototype is introduced, designed to detect such particles within an
industrial fluid. The proposed prototype is
based on an LC oscillator circuit integrated with a planar coil architecture,
sensitive to magnetic changes caused by metal particles. The sensing surface
comprises a planar coil fabricated using standard printed circuit board manufacturing techniques. A manually controllable desktop testing setup was
established in a laboratory environment to evaluate the detection capability of
the sensor. Metal particles were passed through a hose over the planar coil,
causing shifts in the resonance frequency of the LC oscillator. These frequency
changes were measured using an integrated converter and a microcontroller unit, enabling precise
monitoring of the variations. Simultaneous measurements were analyzed
graphically, demonstrating the effectiveness of the prototype in detecting
metallic particles. Ongoing work focuses on improving the architecture of the
prototype to develop a robust device suitable for industrial applications. The implementation of this device
in machinery could reduce maintenance costs and extend equipment lifespan.
