ABSTRACT:
A symmetrical viscosity sensor for measuring the viscosity of fluids such as transmission oil or engine oil. Torsion oscillators are arranged symmetrically on both sides. The viscosity sensor includes a coupling shaft; a torsion oscillator coupled symmetrically to both ends of the coupling shaft; at least one insulator coupled to a center portion of said coupling shaft; a plurality of oscillation means arranged between each torsion oscillator and the insulator; a signal transmission/reception line for transmitting and receiving a driving and detection signal of said oscillation means; and a control unit for controlling said driving and detection signal via said signal transmission/reception line.
