1.
Low Level: The area inside the tank opposite the sensor is filled with air, which has a very low dielectric constant (εr≈1), resulting in a small system capacitance value C1. 2.
Level Reached: When vanadium electrolyte (with a dielectric constant much higher than air, εr typically between 30-60) covers the sensor position, the effective dielectric constant increases sharply, causing the capacitance value to jump significantly to C2. 3.
Intelligent Judgment: The microcontroller inside the sensor monitors the capacitance change in real-time. Upon detecting a preset magnitude of change from C1, it judges the level is present and outputs a clear switch signal or analog signal.
•
Dedicated Algorithms: Effectively suppress interference from temperature changes and tank vibrations. •
Adaptive Calibration: Possesses self-adaptation capability for different tank wall materials (stainless steel, FRP, etc.) and thicknesses.
