Capacitance contact detection: Determine whether there is liquid and distinguish between liquids by detecting the capacitance of the liquid.
Conical head of anti-hanging-liquid design: Reduces the phenomenon of hanging liquid in detecting.
Special circuit design: Even if there are liquid residues, foam, scabs, etc. in the probe part, the appearance of false signals can be avoided by adjusting the sensitivity.
Stability design: With temperature compensation, the liquid level sensor can detect stably in the range of low temperature -25°C and high temperature 75°C. These detailed designs ensure the stability of detection performance to a large extent.
Material: The head is made of PEEK material, the shell is made of 316 stainless steel, with general anti-corrosion performance, M12*1 standard thread, easy to install.

Precautions
The liquid sensor should not be used in the following cases:
- Temperature exceeds 75°C
- Pressure higher than 0.3MP
- There is dry glue on the probe that can't be removed
