The YFV8 oil condition sensor adopts piezoelectric resonant MEMS components and integrates high-precision signal sampling and processing units internally, combined with built-in algorithms, to collect eight physical and chemical parameters including kinematic viscosity, 40 ℃ kinematic viscosity (calculated value), dynamic viscosity, density, moisture, water activity, dielectric constant, moisture content, and temperature.
Technical advantages:
1. Accurate measurement of viscosity, density, and temperature with up to eight parameter outputs through online monitoring sensors;
2. Quick response: The data refresh rate only takes 1 second;
3. The shell is made of stainless steel material, which has excellent corrosion resistance and pressure resistance characteristics. The measurement is not affected by external vibration and is suitable for online monitoring robustness requirements;
4. Compact structure, easy system integration, and on-site calibration of integrated modules.
