The sensor consists of two connected cylinder capacitors. The
lower, smaller capacitor (6) records the oil condition.
Two metal tubes (2+3) which act as capacitor electrodes are
located inside the sensor. The engine oil (4) dielectric is located
between the electrodes.
The electrical material properties of the engine oil change in
accordance with increased wear and additive deterioration.
