XKC-Y28 Liquid Level Sensors Capacitive Level Touchless Compilable Sensor Switch for 12mm+ Flat Containers and Pipelines

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.

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
