3-in-1 Oil Status Sensor
YFV3 sensor adopts a piezoelectric resonant MEMS element, which can automatically detect the density, viscosity, 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 dielectric constant temperature;
- Quick response, with a data refresh rate of only 1 second;
- All stainless steel, excellent chemical corrosion resistance and pressure resistance characteristics, measurement not affected by external vibration, 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/1～1000cP | 0.1cP | ±5% |
