Abstract: A sensor system for inspecting oil, which comprises a micromechanical cell defining a cavity for allowing the entrance/outcome of oil within/from said cavity through respective inlet and outlet. Inside said micromechanical cell there are: first and second transparent protective means; a light source configured to emit incoherent light towards said oil; an opaque plate disposed between said light source and said first transparent protective means, having a pin-hole configured to permit the passage of illumination towards said oil, said pin-hole being located at a first distance from a focussing plane defined by said oil in cavity; an image sensor to capture images of the oil disposed within said cavity located at a second distance from said focussing plane defined by said oil in cavity.

Abstract: A sensor system (1) for inspecting oil, which comprises a micromechanical cell (10) defining a cavity (12), the micromechanical cell (10) being configured for allowing the entrance of oil (5) within said cavity (12) and the outcome of oil (5) from said cavity (12) through respective inlet (11a) and outlet (11b).
