Product Overview:
LCPBA01
is a non-contact liquid level sensor with status indicator and adjustable sensitivity. It is suitable for liquid level detection of various curved, arc-shaped, cylindrical non-metallic containers or pipes, and can provide real-time feedback on the status of the sensor. It is equipped with a 3Pin wiring harness, which can directly collect digital signals and better connect to the microcontroller or other main controller. It is widely used in water tank detection, beverage machine, water pipe liquid level detection, scientific experiment test tube liquid level detection and other scenarios.
The sensor adopts advanced signal processing technology and high-speed signal processing chip, breaking through the influence of container wall thickness and realizing true non-contact detection of liquid level height in closed containers. It is suitable for non-metallic pipes (pipeline outer diameter D≥11MM) or flat containers, without direct contact with liquids, will not be corroded by corrosive liquids such as strong acids and alkalis, and will not be affected by scale or other debris.
Its working principle is to use the inductive capacitance of water to detect whether there is liquid. When there is no liquid approaching 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 and approaches the sensor, the parasitic capacitance of the liquid will couple to this static capacitance, making the final capacitance value of the sensor larger. The changed capacitance signal is then input into the control IC for signal conversion, converting the changed capacitance into a certain amount of change in an electrical signal, and then a certain algorithm is used to detect and judge the degree of this change. When this change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point.
