1st. 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 container wall thickness and realizes the true non-contact of the liquid level in the closed container. Contact detection. The liquid level sensor (probe) is installed on the upper and lower sides of the outer wall of the container to be tested (the high and low levels of the liquid level). The non-metallic container does not need to be opened, and the installation is simple and does not affect production. It can detect the level of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure airtight containers. The liquid level sensor has no special requirements for the material of the liquid medium and container, and can be widely used. XKC-Y28-NO/NC/ RS485 products are specially developed for non-metallic pipes (pipe outer diameter D≥11MM) or flat container liquid level detection. They are relay normally open output and relay normally closed outputand RS485 interface output.
2nd.Product Features 1. XCK-Y28-NO/NC/ RS485 sensor, suitable for non-metallic pipes (pipe outer diameter D≥11MM) or flat containers without direct contact with liquids, It will not be corroded by strong acids or alkalis and other corrosive liquids, and will not be affected by scale or other debris. It can be completed to detect whether there is liquid inside the container or pipeline. 2. Intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, can realize multi-point series connection. 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 durability. 5.

Strong compatibility, penetrating various non-metallic container pipes, such as plastic, glass, ceramics and other containers, the induction pipe wall thickness can reach 20mm; suitable for all kinds of curved, arc, cylindrical containers or pipes Liquid level detection. 7. The voltage can be selected (5V, 12V, 24V), suitable for connecting various circuits and product applications.
3rd.Product Applications 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, the sensor has a certain static capacitance to the ground due to the distributed capacitance on the sensor. When the liquid level slowly rises and approaches 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 capacitance is converted into a change of a certain electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When the change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point
