The High Precision Pump Level Switch Sensor FS-IR22 is a stable and reliable sensor. The level detector sensor is composed of a near-infrared light-emitting diode and a photosensitive receiver, and uses the principle of reflection and refraction at the interface of two different media to detect the change of the liquid level.
The light emitted by the LED is directed into the lens at the top of the sensor. When the liquid is immersed in the lens of the photoelectric level switch, the light is refracted into the liquid, so that the receiver does not receive or can only receive a small amount of light. If there is no liquid, the light from the LED is reflected directly from the lens back to the receiver.
