XKC-Y25 Water Tank Level Sensor

Product Overview:

The intelligent non-contact liquid level sensor (hereinafter referred to as the liquid level sensor) adopts advanced signal processing technology and high-speed signal processing chip, which breaks through the influence of the vessel wall thickness and realizes the real non-contact detection of the liquid level height in the closed vessel. The liquid level sensor (probe) is installed at the upper and lower parts of the outer wall of the measured container (high and low level of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect the production. It can detect the liquid level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure closed containers. The liquid level sensor has no special requirements for the material of liquid medium and container, and can be widely used.

The intelligent non-contact liquid level sensor has four kinds of signal output interfaces, including high and low level output interface, NPN output interface, PNP output interface and RS485 communication interface; Corresponding to four models:

● High and low level output interface - model: XKC-Y25-V

● NPN output interface - model: XKC-Y25-NPN

● PNP output interface - model: XKC-Y25-PNP

● RS485 communication interface - model: XKC-Y25-RS485

Product Characteristics:

1. The non-contact liquid level sensor is applicable to the outer wall of non-metallic containers without direct contact with liquid, and will not be corroded by corrosive liquids such as strong acids and alkalis, and will not be affected by scale or other impurities.

2. Intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, can realize multi-point series connection; It can support high and low level output, NPN, PNP signal output and RS485 communication interface output (it is enough to explain with the manufacturer when selecting the model).

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

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

5. It has high stability, high sensitivity, strong rigid interference ability, and is free from external electromagnetic interference. Special treatment is made for power frequency interference and common mode interference to be compatible with all 5~24V power adapters on the market.

6. Strong compatibility, penetrating various non-metallic containers, such as plastic, glass, ceramic and other containers, with sensing distance up to 20mm; Liquid, powder and particle can be detected.

7. Open collector output mode, 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 approaching the sensor, there is a certain static capacitance on the sensor due to the existence of distributed capacitance. When the liquid level rises slowly and approaches the sensor, the parasitic capacitance of the liquid will be coupled to this static capacitance, so that the final capacitance of the sensor becomes larger, The changed capacitance signal is then input to the control IC for signal conversion, which converts the changed capacitance into the change of some 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 reaches the sensing point.
