6-in-1 Oil Status Sensor
The YFV6 sensor adopts piezoelectric resonant MEMS components, and through an internally integrated high-precision signal sampling and processing unit, combined with built-in algorithms, it can automatically detect six indicators of liquid moisture, density, viscosity, dielectric constant, moisture activity, and temperature in real-time.
Features：
- Online monitoring and sensing for accurate measurement of viscosity, density and temperature up to six parameters;
- Fast response: the data refresh frequency is only 1 s;
- The shell is made of stainless steel, which has excellent corrosion resistance and pressure resistance, and the measurement is not affected by external vibration, which is suitable for online monitoring robustness requirements;
- Compact structure, easy for system integration, and on-site calibration of integrated modules.
