Working Principle
The Y26A sensor detects liquid levels using changes in capacitance. When no liquid is near the sensor, the static capacitance between the sensor and the ground is minimal. As the liquid level rises and comes into proximity, the parasitic capacitance of the liquid combines with the static capacitance, increasing the total capacitance value. This change is processed by the sensor’s control IC, which converts it into an electrical signal. Using a specialized algorithm, the sensor determines whether the liquid level has reached the threshold and outputs the corresponding signal.
The Y26A Thin Tube Liquid Level Sensor is a reliable and efficient solution for precise liquid level detection in small-diameter pipelines and containers, offering robust features and seamless adaptability across multiple industries.
