Product Features:

1. XKC-Y26A non-contact liquid level sensor is suitable for all kinds of non-metallic containers. Detects liquid through the non-metallic container and the outer wall of the pipeline, without direct contact with the liquid, not affected by strong acid,corrosion of corrosive liquids such as alkali, without being affected by scale or other sundries, detect whether there is liquid inside the container or pipeline

2. Intelligent liquid level reference adjustment and liquid level memory function, liquid level state display mode, can realize multi-point serial connection control mode. support high and low level output, NPN, PNP signal output control (just consult us when selecting the model).

3. The detection liquid level is accurate and stable, and it can detect cold, hot and boiling liquids.

4. Pure electronic circuit structure, non-mechanical working mode, stable performance and long service life.

5. High stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with all 5~24V power adapters on the market.

6. It has a wide range of applications and strong sensing ability. It can penetrate and detect the liquid water level in various non-metallic containers and pipelines, such as plastic, glass, ceramic and other containers. The thickness of the sensing tube wall can reach 20mm; it can be applied to various curved surfaces , arc, cylindrical and other irregular containers or pipelines for liquid level detection.

7.Wide voltage range (5~24V), suitable for connecting various circuits and product applications.

Working Principle:

The intelligent non-contact liquid level sensor uses the inductive capacitance of water to detect whether there is liquid. When there is no liquid close to the sensor, due to the existence of distributed capacitance on the sensor, there is a certain static capacitance between the sensor and the ground.When the liquid level slowly rises close to the sensor, the parasitic capacitance of the liquid will be coupled to this static capacitance, making the capacitance value of the sensor larger, and the changed capacitance signal is then input to the control IC for signal conversion.

The changing capacitance is converted into a change of some kind of electrical signal, and then a certain algorithm is used to detect and judge the degree of the change. When the change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point.
