The photoelectric level switch uses advanced optical sensors to manage and control liquid levels with high precision. Utilizing infrared detection, this switch operates based on the principles of light refraction and reflection. When the liquid reaches a high level, it creates a distinct interface between the liquid and the switch. Conversely, at low liquid levels, the interface shifts to air, changing the light reflection received by the internal photodetector. These variations in light intensity directly correspond to different switch states, ensuring reliable and accurate liquid level monitoring for a wide range of industrial applications.
