What's 3 in 1 Oil Water Air Level Sensor

- Jan 06, 2021-

We --EPT Co. has developed a new 3-in-1 oil-water-air detect sensor based on the double-layer tank leak detection sensor.


Working Principle

There are capacitive sensor and photoelectric sensor in the sensing part.

The principle that the dielectric constants of water and oil are very different is used to realize oil-water detection. 

Small changes in water content will cause large changes in oil dielectric constants.


① TRVV Oil-resistant bending cable;

② Metal shell, can be customized, the size shown is the minimum size of metal shell;

③ Sensing part


Normally use for the detection of oil and water leakage in double-walled oil tank interlayers, ground wells, and other spaces
