Product Features:

1. The hand-held liquid level detector is suitable for the outer wall of non-metallic containers without direct contact with the liquid, and will not be corroded by corrosive liquids such as strong acids and alkalis, and will not be affected by scale or other sundries.

2. Intelligent liquid level reference adjustment and liquid level memory function.

3. The detection is accurate and stable, and can detect the boiling water level.

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

5. High stability, high sensitivity, strong anti-interference ability, free from external electromagnetic interference.

6. Strong compatibility, penetrating various non-metallic containers, such as plastic, glass, ceramics and other containers, the sensing distance (container wall thickness) can reach 40mm; liquid, powder, and particles can be detected.

7. Powered by 2 AAA batteries, the batteries are cheap and easy to buy, and there is one NPN output at the end, which is suitable for docking with various devices to improve the flexibility of the product.

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.

scope of applications:

1. Wine vessel inventory detection

2. Grain warehouse inventory detection

3. Pharmaceutical inventory inspection

4. Filling inspection

5. Portable water pipe water shortage detection

6. Applicable to various non-metallic containers to detect liquid level stock
