Oil viscosity sensor

1、Oil viscosity sensor Product Overview

Oil viscosity sensor monitors density, viscosity, and temperature in real time, improving the health of lubricating oil and equipment, and has excellent viscosity anti-interference properties.FV3 Oil viscosity sensor utilizes a piezoelectric resonant MEMS core element, integrating high-precision signal acquisition and processing units with intelligent algorithms to enable the real-time, simultaneous measurement of liquid temperature, dynamic viscosity, and density.

Application Areas: Hydraulic power units, gearboxes, diesel engines, turbines, air compressors, and similar equipment.

2、Oil viscosity sensor Applicable Oils

Industrial Lubricants: Hydraulic oil, gear oil, turbine oil, transformer oil.

Engine Oils: Diesel engine oil, aviation engine oil.

Light Fuels: Gasoline, kerosene, aviation fuel.

3、Oil viscosity sensor Measurement Principle

The FV3Oil viscosity sensor operates based on the principle of piezoelectric resonance. Driven by an electronic unit, its core oscillator maintains a state of resonance; by precisely measuring changes in characteristic parameters—such as resonance frequency, phase, or amplitude—the device directly calculates the viscosity, density, and temperature of the medium.

Its oscillation period T is correlated with the liquid density: ρ = K0 + K1*T + K2*T² (where K0, K1, and K2 are instrument calibration parameters).

Its oscillation quality factor Q is correlated with viscosity: η = C0 + C1*Q + C2*Q² (where C0, C1, and C2 are instrument calibration parameters).

Kinematic viscosity can also be derived using the following formula: µ = η / ρ (where µ represents kinematic viscosity in mm²/s or cSt; η represents dynamic viscosity in mPa·s; and ρ represents density in g/cm³).
