4-in-1 Oil Status Sensor
YFV4 sensor adopts a piezoelectric resonant MEMS element, which can automatically detect the density, viscosity, dielectric constant, and temperature of the liquid in real time through the integrated high-precision signal sampling and processing unit and the built-in algorithm.
Features:
- Imported probe for precise measurement of viscosity, density, and temperature;
- Quick response, with a data refresh rate of only 1 second;
- All stainless steel, excellent corrosion resistance and pressure resistance, suitable for online monitoring robustness requirements;
- Compact structure, easy for system integration, and on-site calibration of integrated modules.
Technical index
Sensor measurement index | |||
Measurement index | Measurement range | Resolution ratio | Measurement accuracy |
Temperature | 0～100℃ | 0.1℃ | ±0.3℃（25℃） |
Dynamic viscosity | 1～400cP or 1～1000cP | 0.1cP | ±5% |
Density | 600～1250kg/m³ | 0.1kg/m³ | ±3% |
